The common feature of these small verticals is that the format is fixed. Therefore, it is very suitable to use OCR technology for automation, greatly reducing labor costs and improving.\n",

At present, research in academia mainly focuses on natural scenes, and the commonly used academic datasets in the OCR field are also natural scenes. There are many studies on these issues. Relatively speaking, identification is more challenging than detection.\n",

+    "In practical applications, especially in a wide range of general scenarios, in addition to the technical difficulties at the algorithm level such as affine transformation, scale problems, insufficient lighting, and shooting blur summarized in the previous section, OCR technology also faces two major difficulties:\n",
+    "1. **Massive data requires OCR to be able to process in real time.** OCR applications are often connected to massive data. Real-time processing of the data is required or hoped for. Real-time model speed is a big challenge.\n",
+    "2. **The end-side application requires that the OCR model is light enough and the recognition speed is fast enough.** OCR applications are often deployed on mobile terminals or embedded hardware. There are generally two modes for terminal-side OCR applications: upload to server vs. terminal-side direct recognition. Considering that the method of uploading to the server has requirements on the network, the real-time performance is low, and the server pressure is high when the request volume is too large, as well as the security of data transmission, we hope to complete the OCR identification directly on the terminal side.

+    "The task of text detection is to locate text regions in the input image. In recent years, research on text detection in academia has been very rich. A class of methods regard text detection as a specific scene in target detection, and improve and adapt based on general target detection algorithms. For example, TextBoxes[1] is based on one-stage target detector SSD. The algorithm [2] adjusts the target frame to fit text lines with extreme aspect ratios, while CTPN [3] is improved based on the Faster RCNN [4] architecture. However, there are still some differences between text detection and target detection in the target information and the task itself. For example, the text is generally larger in length and width, often in the shape of \"stripes\", and the text lines may be denser, curved text, etc. Therefore, many algorithms dedicated to text detection have been derived, such as EAST[5], PSENet[6], DBNet[7] and so on.\n",

Algorithms based on regression draw on general object detection algorithms, by setting the anchor regression detection frame, or directly doing pixel regression. This type of method has a better detection effect on regular-shaped text, but the detection effect on irregularly-shaped text will be relatively poor. For example, CTPN [3] has better detection effect on horizontal text, but poor detection effect on oblique and curved text. SegLink [8] is more effective for long text, but has limited effect on sparsely distributed text; algorithm based on segmentation Introduced Mask-RCNN [9], this type of algorithm can reach a higher level in various scenes and texts of various shapes, but the disadvantage is that the post-processing is generally more complicated, so there are often speed problems.

+    "**1.2: What data sets are used in the Chinese ultra-lightweight and general models in the PaddleOCR project? How many samples were trained, what configuration of GPUs, how many epochs were run, and how long did they run?**\n",
+    "\n",
+    "**A**: For the ultra-lightweight DB detection model, the training data includes open source data sets lsvt, rctw, CASIA, CCPD, MSRA, MLT, BornDigit, iflytek, SROIE and synthetic data sets, etc. The total data volume is 10W, The data set is divided into 5 parts. A random sampling strategy is used during training. The training takes about 500 epochs on a 4-card V100GPU, which takes 3 days.\n",
+    "\n",
+    "\n",
+    "**1.3 Does the text detection training label require specific text labeling? What does the \"###\" in the label mean?**\n",
+    "\n",
+    "**A**: Text detection training only needs the coordinates of the text area. The label can be four or fourteen points, arranged in the order of upper left, upper right, lower right, and lower left. The label file provided by PaddleOCR contains text fields. For unclear text in the text area, ### will be used instead. When training the detection model, the text field in the label will not be used.\n",

+    "**1.5 For some large-sized document images, DB will have more missed inspections during inspection. How to avoid this kind of missed inspections?**\n",
+    "\n",
+    "**A**: First of all, you need to determine whether the model is not well-trained or is the problem handled during prediction. If the model is not well trained, it is recommended to add more data for training, or add more data to enhance it during training.\n",
+    "If the problem is that the predicted image is too large, you can increase the longest side setting parameter [det_limit_side_len] entered during prediction [det_limit_side_len](https://github.com/PaddlePaddle/PaddleOCR/blob/8b656a3e13631dfb1ac21d2095d4d4a4993ef710/tools/infer/utility.py?_pjax=%23js-repo-pjax-container%2C%20div%5Bitemtype%3D%22http%3A%2F%2Fschema.org%2FSoftwareSourceCode%22%5D%20main%2C%20%5Bdata-pjax-container%5D#L47), which is 960 by default.\n",
+    "Secondly, you can observe whether the missed text has segmentation results by visualizing the post-processed segmentation map. If there is no segmentation result, the model is not well trained. If there is a complete segmentation area, it means that it is a problem of post-prediction processing. In this case, it is recommended to adjust [DB post-processing parameters](https://github.com/PaddlePaddle/PaddleOCR/blob/8b656a3e13631dfb1ac21d2095d4d4a4993ef710/tools/infer/utility.py?_pjax=%23js-repo-pjax-container%2C%20div%5Bitemtype%3D%22http%3A%2F%2Fschema.org%2FSoftwareSourceCode%22%5D%20main%2C%20%5Bdata-pjax-container%5D#L51-L53)。\n",

+    "\n",
+    "**1.6 The problem of missed detection of DB model bending text (such as a slightly deformed document image)?**\n",
+    "\n",
+    "**A**: When calculating the average score of the text box in the DB post-processing, it is the average score of the rectangle area, which is easy to cause the missed detection of the curved text. The average score of the polygon area has been added, which will be more accurate, but the speed is somewhat different. Decrease, can be selected as needed, and you can view the [Visual Contrast Effect] (https://github.com/PaddlePaddle/PaddleOCR/pull/2604) in the relevant pr.

+    "**1.7 For simple OCR tasks with low accuracy requirements, how many data sets do I need to prepare?**\n",
+    "\n",
+    "**A**: (1) The amount of training data is related to the complexity of the problem to be solved. The greater the difficulty and the higher the accuracy requirements, the greater the data set requirements, and in general, the more training data in practice, the better the effect.\n",
+    "\n",
+    "(2) For scenes with low accuracy requirements, the amount of data required for detection tasks and recognition tasks is different. For inspection tasks, 500 images can guarantee the basic inspection results. For recognition tasks, it is necessary to ensure that the number of line text images in which each character in the recognition dictionary appears in different scenes needs to be greater than 200 (for example, if there are 5 words in the dictionary, each word needs to appear in more than 200 pictures, then The minimum required number of images should be between 200-1000), so that the basic recognition effect can be guaranteed.\n",
+    "\n",

+    "**1.8 How to get more data when the amount of training data is small?**\n",
+    "\n",
+    "**A**: When the amount of training data is small, you can try the following three ways to get more data: (1) Collect more training data manually, the most direct and effective way. (2) Basic image processing or transformation based on PIL and opencv. For example, the three modules of ImageFont, Image, ImageDraw in PIL write text into the background, opencv's rotating affine transformation, Gaussian filtering and so on. (3) Synthesize data using data generation algorithms, such as algorithms such as pix2pix.\n",
+    "\n",
+    "\n",
+    "**1.9 How to replace the backbone of text detection/recognition?**\n",
+    "\n",
+    "A: Whether it is text detection or text recognition, the choice of backbone network is a trade-off between prediction effect and prediction efficiency. Generally, if you choose a larger-scale backbone network, such as ResNet101_vd, the detection or recognition will be more accurate, but the prediction time will increase accordingly. However, choosing a smaller-scale backbone network, such as MobileNetV3_small_x0_35, will predict faster, but the accuracy of detection or recognition will be greatly reduced. Fortunately, the detection or recognition effects of different backbone networks are positively correlated with the image 1000 classification task in the ImageNet dataset. PaddleClas, a flying paddle image classification suite, summarizes 23 series of classification network structures such as ResNet_vd, Res2Net, HRNet, MobileNetV3, GhostNet, etc. The top1 recognition accuracy rate of the above image classification task, GPU (V100 and T4) and CPU (Snapdragon 855) The prediction time-consuming and the corresponding 117 pre-training model download addresses.\n",
+    "\n",
+    "(1) The replacement of the text detection backbone network is mainly to determine 4 stages similar to ResNet to facilitate the integration of subsequent detection heads similar to FPN. In addition, for the text detection problem, the classification pre-training model trained by ImageNet can accelerate the convergence and improve the effect.\n",
+    "\n",
+    "(2) The replacement of the backbone network for text recognition requires attention to the drop position of the network width and height stride. Since text recognition generally has a large ratio of width to height, the frequency of height reduction is less, and the frequency of width reduction is more. You can refer to [Changes to the MobileNetV3 backbone network in PaddleOCR](https://github.com/PaddlePaddle/PaddleOCR/blob/release%2F2.3/ppocr/modeling/backbones/rec_mobilenet_v3.py)。\n",
+    "\n",
+    "\n",
+    "**1.10 How to finetune the detection model, such as freezing the previous layer or learning with a small learning rate for some layers?**\n",
+    "\n",
+    "**A**: If you freeze certain layers, you can set the stop_gradient property of the variable to True, so that all the parameters before calculating this variable will not be updated, refer to: https://www.paddlepaddle.org.cn/documentation/docs/zh/develop/faq/train_cn.html#id4\n",
+    "\n",
+    "If learning with a smaller learning rate for some layers is not very convenient in the static graph, one method is to set a fixed learning rate for the weight attribute when the parameters are initialized, refer to: https://www.paddlepaddle.org.cn/documentation/docs/en/develop/api/paddle/fluid/param_attr/ParamAttr_cn.html#paramattr\n",
+    "\n",
+    "In fact, our experiment found that directly loading the model to fine-tune without setting different learning rates of certain layers, the effect is also good.\n",
+    "\n",
+    "**1.11 In the preprocessing part of DB, why should the length and width of the picture be processed into multiples of 32?**\n",
+    "\n",
+    "**A**: It is related to the stride of the network downsampling. Take the resnet backbone network under inspection as an example. After the image is input to the network, it needs to be downsampled by 2 times for 5 times, a total of 32 times. Therefore, it is recommended that the input image size be a multiple of 32.\n",
+    "\n",
+    "\n",
+    "**1.12 In the PP-OCR series models, why does the backbone network for text detection not use SEBlock?**\n",
+    "\n",
+    "**A**: The SE module is an important module of the MobileNetV3 network. Its purpose is to estimate the importance of each feature channel of the feature map, assign weights to each feature of the feature map, and improve the expressive ability of the network. However, for text detection, the resolution of the input network is relatively large, generally 640\\*640. It is difficult to use the SE module to estimate the importance of each feature channel of the feature map. The network improvement ability is limited, but the module is relatively time-consuming. In the PP-OCR system, the backbone network for text detection does not use the SE module. Experiments also show that when the SE module is removed, the size of the ultra-lightweight model can be reduced by 40%, and the text detection effect is basically not affected.

+    "#### 2.1.1 Algorithm Based on CTC\n",
+    "\n",
+    "The most typical algorithm based on CTC is CRNN (Convolutional Recurrent Neural Network) [1], and its feature extraction part uses mainstream convolutional structures, commonly used ResNet, MobileNet, VGG, etc. Due to the particularity of text recognition tasks, there is a large amount of contextual information in the input data. The convolution kernel characteristics of convolutional neural networks make it more focused on local information and lack long-dependent modeling capabilities, so it is difficult to use only convolutional networks. Dig into the contextual connections between texts. In order to solve this problem, the CRNN text recognition algorithm introduces the bidirectional LSTM (Long Short-Term Memory) to enhance the context modeling. Experiments prove that the bidirectional LSTM module can effectively extract the context information in the picture. Finally, the output feature sequence is input to the CTC module, and the sequence result is directly decoded. This structure has been verified to be effective and widely used in text recognition tasks. Rosetta [2] is a recognition network proposed by FaceBook, which consists of a fully convolutional model and CTC. Gao Y [3] et al. used CNN convolution instead of LSTM, with fewer parameters, and the performance improvement accuracy was the same.\n",

+    "#### 2.1.2 Sequence2Sequence algorithm\n",
+    "\n",
+    "In the Sequence2Sequence algorithm, the Encoder encodes all input sequences into a unified semantic vector, which is then decoded by the Decoder. In the decoding process of the decoder, the output of the previous moment is continuously used as the input of the next moment, and the decoding is performed in a loop until the stop character is output. The general encoder is an RNN. For each input word, the encoder outputs a vector and hidden state, and uses the hidden state for the next input word to get the semantic vector in a loop; the decoder is another RNN, which receives the encoder Output a vector and output a series of words to create a transformation. Inspired by Sequence2Sequence in the field of translation, Shi [4] proposed an attention-based codec framework to recognize text. In this way, rnn can learn character-level language models hidden in strings from training data.\n",

+    "The above two algorithms have very good effects on regular text, but due to the limitations of network design, this type of method is difficult to solve the task of irregular text recognition of bending and rotation. In order to solve such problems, some algorithm researchers have proposed a series of improved algorithms on the basis of the above two types of algorithms.\n",
+    "\n",
+    "### 2.2 Irregular Text Recognition\n",
+    "\n",
+    "* Irregular text recognition algorithms can be divided into 4 categories: correction-based methods; Attention-based methods; segmentation-based methods; and Transformer-based methods.\n",
+    "\n",
+    "#### 2.2.1 Correction-based Method\n",
+    "\n",
+    "The correction-based method uses some visual transformation modules to convert irregular text into regular text as much as possible, and then uses conventional methods for recognition.\n",
+    "\n",
+    "The RARE [4] model first proposed a correction scheme for irregular text. The entire network is divided into two main parts: a spatial transformation network STN (Spatial Transformer Network) and a recognition network based on Sequence2Squence. Among them, STN is the correction module. Irregular text images enter STN and are transformed into a horizontal image through TPS (Thin-Plate-Spline). This transformation can correct curved and transmissive text to a certain extent, and send it to sequence recognition after correction. Network for decoding.\n",
+    "\n",
+    "<center><img src=https://ai-studio-static-online.cdn.bcebos.com/66406f89507245e8a57969b9bed26bfe0227a8cf17a84873902dd4a464b97bb5 width=\"600\"></center>\n",
+    "<center>Figure 8:  RARE structure diagram </center>\n",
+    "\n",
+    "The RARE paper pointed out that this method has greater advantages in irregular text data sets, especially comparing the two data sets CUTE80 and SVTP, which are more than 5 percentage points higher than CRNN, which proves the effectiveness of the correction module. Based on this [6] also combines a text recognition system with a spatial transformation network (STN) and an attention-based sequence recognition network.\n",
+    "\n",
+    "Correction-based methods have better migration. In addition to Attention-based methods such as RARE, STAR-Net [5] applies correction modules to CTC-based algorithms, which is also a good improvement compared to traditional CRNN.\n",
+    "\n",
+    "#### 2.2.2 Attention-based Method\n",
+    "\n",
+    "The Attention-based method mainly focuses on the correlation between the parts of the sequence. This method was first proposed in the field of machine translation. It is believed that the result of the current word in the process of text translation is mainly affected by certain words, so it needs to be The decisive word has greater weight. The same is true in the field of text recognition. When decoding the encoded sequence, each step selects the appropriate context to generate the next state, which is conducive to obtaining more accurate results.\n",
+    "\n",
+    "R^2AM [7] first introduced Attention into the field of text recognition. The model first extracts the encoded image features from the input image through a recursive convolutional layer, and then uses the implicitly learned character-level language statistics to decode the output through a recurrent neural network character. In the decoding process, the Attention mechanism is introduced to realize soft feature selection to make better use of image features. This selective processing method is more in line with human intuition.\n",
+    "\n",
+    "<center><img src=https://ai-studio-static-online.cdn.bcebos.com/a64ef10d4082422c8ac81dcda4ab75bf1db285d6b5fd462a8f309240445654d5 width=\"600\"></center>\n",
+    "<center>Figure 9:  R^2AM structure drawing </center>\n",
+    "\n",
+    "A large number of algorithms will be explored and updated in the field of Attention in the future. For example, SAR[8] extends 1D attention to 2D attention. The RARE mentioned in the correction module is also a method based on Attention. Experiments prove that the Attention-based method has a good accuracy improvement compared with the CTC method.\n",
+    "\n",

+    "\n",
+    "\n",
+    "#### 2.2.3 Method Based on Segmentation\n",
+    "\n",
+    "The method based on segmentation is to treat each character of the text line as an independent individual, and it is easier to recognize the segmented individual characters than to recognize the entire text line after correction. It attempts to locate the position of each character in the input text image, and applies a character classifier to obtain these recognition results, simplifying the complex global problem into a local problem solving, and it has a relatively good effect in the irregular text scene. However, this method requires character-level labeling, and there is a certain degree of difficulty in data acquisition. Lyu [9] et al. proposed an instance word segmentation model for word recognition, which uses a method based on FCN (Fully Convolutional Network) in its recognition part. [10] Considering the problem of text recognition from a two-dimensional perspective, a character attention FCN is designed to solve the problem of text recognition. When the text is bent or severely distorted, this method has better positioning results for both regular and irregular text.\n",

+    "\n",
+    "\n",
+    "#### 2.2.4 Transformer-based Method\n",
+    "\n",

As mentioned in the regular text recognition part, CNN has limitations in long-dependency modeling. The Transformer structure just solves this problem. It can focus on global information in the feature extractor and can replace additional context modeling modules (LSTM ).\n",

The Encoder is composed of multiple blocks stacked by MultiHeadAttentionLayer and Positionwise Feedforward Layer.

There are also some algorithms that use Transformer's Decoder module to decode, which can obtain stronger semantic information than traditional RNNs, and parallel computing has higher efficiency.\n",

In addition, SRN also uses Transformer's Eecoder as a semantic module to integrate the visual information and semantic information of the picture, which has greater benefits in irregular text such as occlusion and blur.\n",

Then, pdf2table proposed by Yildiz[2] et al. is the first method for table recognition on PDF documents, which utilizes some unique information of PDF files (such as text, drawing paths and other information that are difficult to obtain in image documents) to assist with table recognition.

Schreiber Sebastian [11] et al. proposed DeepDeSRT, which uses Faster RCNN for table detection and FCN semantic segmentation model for Table structure row and column detection, but this method uses two independent models to solve these two problems. Prasad Devashish [4] et al. proposed an end-to-end deep learning method CascadeTabNet, which uses the Cascade Mask R-CNN HRNet model to perform table detection and structure recognition at the same time, which solves the problem of using two independent methods to process table recognition in the past.

At the same time, additional spatial semantic features are added to TableNet during training to further improve the performance of the model. Zheng Xinyi [13] et al. proposed a system framework GTE for table recognition, using a cell detection network to guide the training of the table detection network, and proposed a hierarchical network and a new clustering-based cell structure recognition algorithm, the framework can be connected to the back of any target detection model to facilitate the training of different table recognition algorithms. Previous research mainly focused on parsing from scanned PDF documents with a simple layout and well-aligned table images. However, the tables in real scenes are generally complex and may have serious deformation, bending or occlusion. Therefore, Long Rujiao [14] et al. also constructed a table recognition data set WTW in a realistic complex scene, and proposed a Cycle-CenterNet method, which uses the cyclic pairing module optimization and the proposed new pairing loss to accurately group discrete units into structured In the table, the performance of table recognition is improved.\n",

+    "In recent years, with the rise of Graph Convolutional Networks (Graph Convolutional Network), some researchers have tried to apply graph neural networks to table structure recognition problems. Qasim Shah Rukh [20] et al. converted the table structure recognition problem into a graph problem compatible with graph neural networks, and designed a novel differentiable architecture that can not only take advantage of the advantages of convolutional neural networks to extract features, but also The advantages of the effective interaction between the vertices of the graph neural network can be used, but this method only uses the location features of the cells, and does not use the semantic features. Chi Zewen [19] et al. proposed a novel graph neural network, GraphTSR, for table structure recognition in PDF files. It takes cells in the table as input, and then uses the characteristics of the edges and nodes of the graph to be connected. Predicting the relationship between cells to identify the table structure solves the problem of cell identification across rows or columns to a certain extent. Xue Wenyuan [21] et al. reformulated the problem of table structure recognition as table map reconstruction, and proposed an end-to-end method for table structure recognition, TGRNet, which includes cell detection branch and cell logic location branch. , These two branches jointly predict the spatial and logical positions of different cells, which solves the problem that the previous method did not pay attention to the logical position of cells.\n",

Although LayoutLM combines text, location and image information, the image information is fused in the training of downstream tasks, so the multi-modal fusion of the three types of information is not sufficient. Based on LayoutLM, LayoutLMv2 [7] integrates image information with text and layout information in the pre-training stage through transformers, and also adds a spatial perception self-attention mechanism to the Transformer to assist the model to better integrate visual and text features. Although LayoutLMv2 fuses text, location and image information in the pre-training stage, the visual features learned by the model are not fine enough due to the limitation of the pre-training task. StrucTexT [8] based on the previous multi-modal methods, proposed two new tasks, Sentence Length Prediction (SLP) and Paired Boxes Direction (PBD) in the pre-training task to help the network learn fine visual features. Among them, the SLP task makes the model Learn the length of the text segment, the PDB task allows the model to learn the matching relationship between Box directions. Through these two new pre-training tasks, the deep cross-modal fusion between text, visual and layout information can be accelerated.\n",

+    "### 1.1 Preliminary Knowledge\n",
+    "\n",
+    "The \"learning\" of deep learning has been developed from the content of neurons, perceptrons, and multilayer neural networks in machine learning. Therefore, understanding the basic machine learning algorithms is of great help to the understanding and application of deep learning. The \"deepness\" of deep learning is embodied in a series of vector-based mathematical operations such as convolution and pooling used in the process of processing a large amount of information. If you lack the theoretical foundation of the two, you can learn from teacher Li Hongyi's [Linear Algebra](https://aistudio.baidu.com/aistudio/course/introduce/2063) and [Machine Learning](https://aistudio.baidu.com/aistudio/course/introduce/1978) courses.\n",
