C# 通用OCR识别 文字识别 中文识别

软件说明

基于以下两个开源项目，做了再次封装

https://github.com/paddlepaddle/PaddleOCR

PaddleOCRSharp: 本项目是一个基于PaddleOCR的C++代码修改并封装的.NET的OCR工具类库。包含文本识别、文本检测、基于文本检测结果的统计分析的表格识别功能，同时针对小图识别不准的情况下，做了优化，提高识别准确率。包含总模型仅8.6M的超轻量级中文OCR，单模型支持中英文数字组合识别、竖排文本识别、长文本识别。同时支持多种文本检测。

可以一键开启服务；

自带模型，可离线部署；

自带C++相关动态库；
