+# PaddleStructure
+
+PaddleStructure is an OCR toolkit for complex layout analysis. It can divide document data in the form of pictures into **text, table, title, picture and list** 5 types of areas, and extract the table area as excel
+## 1. Quick start
+
+### install
+
+**install layoutparser**
+```sh
+pip3 install https://paddleocr.bj.bcebos.com/whl/layoutparser-0.0.0-py3-none-any.whl
+```
+**install paddlestructure**
+
+install by pypi
+
+```bash
+pip install paddlestructure
+```
+
+build own whl package and install
+```bash
+python3 setup.py bdist_wheel
+pip3 install dist/paddlestructure-x.x.x-py3-none-any.whl # x.x.x is the version of paddlestructure
+```
+
+### 1.2 Use
+
+#### 1.2.1 Use by command line
+
+```bash
+paddlestructure --image_dir=../doc/table/1.png
+```
+
+#### 1.2.2 Use by code
+
+```python
+import os
+import cv2
+from paddlestructure import PaddleStructure,draw_result,save_res
+
+table_engine = PaddleStructure(show_log=True)
+
+save_folder = './output/table'
+img_path = '../doc/table/1.png'
+img = cv2.imread(img_path)
+result = table_engine(img)
+save_res(result, save_folder,os.path.basename(img_path).split('.')[0])
+
+for line in result:
+    print(line)
+
+from PIL import Image
+
+font_path = '../doc/fonts/simfang.ttf' # PaddleOCR下提供字体包
+image = Image.open(img_path).convert('RGB')
+im_show = draw_result(image, result,font_path=font_path)
+im_show = Image.fromarray(im_show)
+im_show.save('result.jpg')
+```
+
+#### 1.2.3 Parameter Description：
+
+| Parameter            | Description                                     | Default value                                        |
+| --------------- | ---------------------------------------- | ------------------------------------------- |
+| output          | The path where excel and recognition results are saved                | ./output/table                              |
+| table_max_len   | The long side of the image is resized in table structure model  | 488                                         |
+| table_model_dir | inference model path of table structure model          | None                                        |
+| table_char_type | dict path of table structure model                 | ../ppocr/utils/dict/table_structure_dict.tx |
+
+Most of the parameters are consistent with the paddleocr whl package, see [doc of whl](../doc/doc_en/whl_en.md)
+
+After running, each image will have a directory with the same name under the directory specified in the output field. Each table in the picture will be stored as an excel, and the excel file name will be the coordinates of the table in the image.
+
+## 2. PaddleStructure Pipeline
+
+the process is as follows
+![pipeline](../doc/table/pipeline_en.jpg)
+
+In PaddleStructure, the image will be analyzed by layoutparser first. In the layout analysis, the area in the image will be classified, including **text, title, image, list and table** 5 categories. For the first 4 types of areas, directly use the PP-OCR to complete the text detection and recognition. The table area will  be converted to an excel file of the same table style via Table OCR.
+
+### 2.1 LayoutParser
+
+Layout analysis divides the document data into regions, including the use of Python scripts for layout analysis tools, extraction of special category detection boxes, performance indicators, and custom training layout analysis models. For details, please refer to [document](layout/README.md).
+
+### 2.2 Table OCR
+
+Table OCR converts table image into excel documents, which include the detection and recognition of table text and the prediction of table structure and cell coordinates. For detailed, please refer to [document](table/README.md)
+
+### 3. Predictive by inference engine
+
+Use the following commands to complete the inference. 
+
+```python
+python3 table/predict_system.py --det_model_dir=path/to/det_model_dir --rec_model_dir=path/to/rec_model_dir --table_model_dir=path/to/table_model_dir --image_dir=../doc/table/1.png --rec_char_dict_path=../ppocr/utils/dict/table_dict.txt --table_char_dict_path=../ppocr/utils/dict/table_structure_dict.txt --rec_char_type=EN --det_limit_side_len=736 --det_limit_type=min --output ../output/table
+```
+After running, each image will have a directory with the same name under the directory specified in the output field. Each table in the picture will be stored as an excel, and the excel file name will be the coordinates of the table in the image.

+
+## 2. PaddleStructure Pipeline
+
+流程如下
+![pipeline](../doc/table/pipeline.jpg)
+
+在PaddleStructure中，图片会先经由layoutparser进行版面分析，在版面分析中，会对图片里的区域进行分类，包括**文字、标题、图片、列表和表格**5类。对于前4类区域，直接使用PP-OCR完成对应区域文字检测与识别。对于表格类区域，经过Table OCR处理后，表格图片转换为相同表格样式的Excel文件。
+
+### 2.1 LayoutParser
+
+版面分析对文档数据进行区域分类，其中包括版面分析工具的Python脚本使用、提取指定类别检测框、性能指标以及自定义训练版面分析模型，详细内容可以参考[文档](layout/README.md)。
+
+### 2.2 Table OCR
+
+Table OCR将表格图片转换为excel文档，其中包含对于表格文本的检测和识别以及对于表格结构和单元格坐标的预测，详细说明参考[文档](table/README_ch.md)
+
+### 3. 预测引擎推理
+
+使用如下命令即可完成预测引擎的推理
+
+```python
+python3 table/predict_system.py --det_model_dir=path/to/det_model_dir --rec_model_dir=path/to/rec_model_dir --table_model_dir=path/to/table_model_dir --image_dir=../doc/table/1.png --rec_char_dict_path=../ppocr/utils/dict/table_dict.txt --table_char_dict_path=../ppocr/utils/dict/table_structure_dict.txt --rec_char_type=EN --det_limit_side_len=736 --det_limit_type=min --output ../output/table
+```
+运行完成后，每张图片会output字段指定的目录下有一个同名目录，图片里的每个表格会存储为一个excel，excel文件名为表格在图片里的坐标。

 ### 2.1 Train
-TBD
+
+In this chapter, we only introduce the training of the table structure model, For model training of [text detection](../../doc/doc_en/detection_en.md) and [text recognition](../../doc/doc_en/recognition_en.md), please refer to the corresponding documents
+
+#### data preparation  
+The training data uses public data set [PubTabNet](https://arxiv.org/abs/1911.10683 ), Can be downloaded from the official [website](https://github.com/ibm-aur-nlp/PubTabNet) 。The PubTabNet data set contains about 500,000 images, as well as annotations in html format。
+
+#### Start training  
+*If you are installing the cpu version of paddle, please modify the `use_gpu` field in the configuration file to false*
+```shell
+# single GPU training
+python3 tools/train.py -c configs/table/table_mv3.yml
+# multi-GPU training
+# Set the GPU ID used by the '--gpus' parameter.
+python3 -m paddle.distributed.launch --gpus '0,1,2,3' tools/train.py -c configs/table/table_mv3.yml
+```
+
+In the above instruction, use `-c` to select the training to use the `configs/table/table_mv3.yml` configuration file.
+For a detailed explanation of the configuration file, please refer to [config](../../doc/doc_en/config_en.md).
+
+#### load trained model and continue training
+
+If you expect to load trained model and continue the training again, you can specify the parameter `Global.checkpoints` as the model path to be loaded.
+
+```shell
+python3 tools/train.py -c configs/table/table_mv3.yml -o Global.checkpoints=./your/trained/model
+```
+
+**Note**: The priority of `Global.checkpoints` is higher than that of `Global.pretrain_weights`, that is, when two parameters are specified at the same time, the model specified by `Global.checkpoints` will be loaded first. If the model path specified by `Global.checkpoints` is wrong, the one specified by `Global.pretrain_weights` will be loaded.

-## 1. Introduction to pipeline
-
-PaddleStructure is a toolkit for complex layout text OCR, the process is as follows
-
-![pipeline](../doc/table/pipeline.png)
-
-In PaddleStructure, the image will be analyzed by layoutparser first. In the layout analysis, the area in the image will be classified, and the OCR process will be carried out according to the category.
-
-Currently layoutparser will output five categories:
-1. Text
-2. Title
-3. Figure
-4. List
-5. Table
-   
-Types 1-4 follow the traditional OCR process, and 5 follow the Table OCR process.
-
-## 2. LayoutParser
-
-
-## 3. Table OCR
-
-[doc](table/README.md)
-
-## 4. Predictive by inference engine
-
-Use the following commands to complete the inference
-```python
-python3 table/predict_system.py --det_model_dir=path/to/det_model_dir --rec_model_dir=path/to/rec_model_dir --table_model_dir=path/to/table_model_dir --image_dir=../doc/table/1.png --rec_char_dict_path=../ppocr/utils/dict/table_dict.txt --table_char_dict_path=../ppocr/utils/dict/table_structure_dict.txt --rec_char_type=EN --det_limit_side_len=736 --det_limit_type=min --output ../output/table
-```
-After running, each image will have a directory with the same name under the directory specified in the output field. Each table in the picture will be stored as an excel, and the excel file name will be the coordinates of the table in the image.
