输入图像经过特征提取送入四个分支,分别是:文本边缘偏移量预测TBO模块,文本中心线预测TCL模块,文本方向偏移量预测TDO模块,以及文本字符分类图预测TCC模块。
其中TBO以及TCL的输出经过后处理后可以得到文本的检测结果,TCL、TDO、TCC负责文本识别。
其检测识别效果图如下:

本节以totaltext数据集为例,介绍PaddleOCR中端到端模型的训练、评估与测试。
### 准备数据
下载解压[totaltext](https://github.com/cs-chan/Total-Text-Dataset/blob/master/Dataset/README.md)数据集到PaddleOCR/train_data/目录,数据集组织结构:
