PaddleSegSharp 是一个基于百度飞桨PaddleSeg项目的人像分割模块而开发的.NET的工具类库。
PaddleSegSharp 中PaddleSeg.dll文件是基于开源项目最新发布版本PaddleSeg PaddleSeg的版本修改而成的C++动态库，基于opencv的x64编译而成的。
PaddleSeg是基于飞桨PaddlePaddle的端到端图像分割套件，内置45+模型算法及140+预训练模型，支持配置化驱动和API调用开发方式，打通数据标注、模型开发、训练、压缩、部署的全流程，提供语义分割、交互式分割、Matting、全景分割四大分割能力，助力算法在医疗、工业、遥感、娱乐等场景落地应用。
本项目只能在X64的CPU上编译和使用，只能在avx指令集上的CPU上使用，目前仅支持windows平台。
PaddleSegSharp 支持飞桨人像抠图的所有模型。PP-MattingV2-512、PP-Matting-512、PP-Matting-1024、PP-HumanMatting、MODNet-MobileNetV2。 默认使用MODNet-MobileNetV2模型。
1、新建winform项目
2、添加引用PaddleSegSharp ，使用NuGet 搜索添加PaddleSegSharp
3、窗体上添加图片显示控件以及按钮
