+# PaddleStructure
+
+## 1. Introduction to pipeline
+
+PaddleStructure is a toolkit for complex layout text OCR, the process is as follows
+
+
+
+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

+## 4. PaddleStructure whl package introduction
+
+### 4.1 Use
+
+4.1.1 Use by code
+```python
+import cv2
+from paddlestructure import PaddleStructure,draw_result
+
+table_engine = PaddleStructure(
+ output='./output/table',

+img = cv2.imread(img_path)
+result = table_engine(img)
+for line in result:
+ print(line)
+
+from PIL import Image
+
+font_path = 'path/tp/PaddleOCR/doc/fonts/simfang.ttf'
+image = Image.open(img_path).convert('RGB')
+im_show = draw_result(image, result,font_path=font_path)

+im_show.save('result.jpg')
+```
+

+```bash
+paddlestructure --image_dir=../doc/table/1.png
+```
+
+### 参数说明
+大部分参数和paddleocr whl包保持一致，见 [whl包文档](../doc/doc_ch/whl.md)
+
+| 字段 | 说明 | 默认值 |
+|------------------------|------------------------------------------------------|------------------|
+| output | excel和识别结果保存的地址 | ./output/table |
+| structure_max_len | structure模型预测时，图像的长边resize尺度 | 488 |

+# Table structure and content prediction
+
+## 1. pipeline
+The ocr of the table mainly contains three models
+1. Single line text detection-DB
+2. Single line text recognition-CRNN
+3. Table structure and cell coordinate prediction-RARE
+
+The table ocr flow chart is as follows
+
+
+
+1. The coordinates of single-line text is detected by DB model, and then sends it to the recognition model to get the recognition result.
+2. The table structure and cell coordinates is predicted by RARE model.
+3. The recognition result of the cell is combined by the coordinates, recognition result of the single line and the coordinates of the cell.
+4. The cell recognition result and the table structure together construct the html string of the table.
+
+## 2. How to use
+
+
+### 2.1 Train
+TBD
+
+### 2.2 Eval
+First cd to the PaddleOCR/ppstructure directory
+
+The table uses TEDS (Tree-Edit-Distance-based Similarity) as the evaluation metric of the model. Before the model evaluation, the three models in the pipeline need to be exported as inference models (we have provided them), and the gt for evaluation needs to be prepared. Examples of gt are as follows:
+```json
+{"PMC4289340_004_00.png": [["", "", "", "", "", "| ", " | ", "", " | ", "", " | ", "
", "", "", "", "| ", " | ", "", " | ", "", " | ", "
", "", "
", "", ""], [[1, 4, 29, 13], [137, 4, 161, 13], [215, 4, 236, 13], [1, 17, 30, 27], [137, 17, 147, 27], [215, 17, 225, 27]], [["", "F", "e", "a", "t", "u", "r", "e", ""], ["", "G", "b", "3", " ", "+", ""], ["", "G", "b", "3", " ", "-", ""], ["", "P", "a", "t", "i", "e", "n", "t", "s", ""], ["6", "2"], ["4", "5"]]]}
+```
+In gt json, the key is the image name, the value is the corresponding gt, and gt is a list composed of four items, and each item is
+1. HTML string list of table structure
+2. The coordinates of each cell (not including the empty text in the cell)
+3. The text information in each cell (not including the empty text in the cell)
+4. The text information in each cell (including the empty text in the cell)
+
+Use the following command to evaluate. After the evaluation is completed, the teds indicator will be output.
+```python
+python3 table/eval_table.py --det_model_dir=path/to/det_model_dir --rec_model_dir=path/to/rec_model_dir --structure_model_dir=path/to/structure_model_dir --image_dir=../doc/table/1.png --rec_char_dict_path=../ppocr/utils/dict/table_dict.txt --structure_char_dict_path=../ppocr/utils/dict/table_structure_dict.txt --rec_char_type=EN --det_limit_side_len=736 --det_limit_type=min --gt_path=path/to/gt.json
+```
+
+
+### 2.3 Inference
+First cd to the PaddleOCR/ppstructure directory
+
+```python
+python3 table/predict_table.py --det_model_dir=path/to/det_model_dir --rec_model_dir=path/to/rec_model_dir --structure_model_dir=path/to/structure_model_dir --image_dir=../doc/table/1.png --rec_char_dict_path=../ppocr/utils/dict/table_dict.txt --structure_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, the excel sheet of each picture will be saved in the directory specified by the table_output field

表格使用 TEDS(Tree-Edit-Distance-based Similarity) 作为模型的评估指标。在进行模型评估之前，需要将pipeline中的三个模型分别导出为inference模型(我们已经提供好)，还需要准备评估的gt， gt示例如下:
