C# OpenCvSharp 部署3D人脸重建3DDFA-V3

说明

地址：https://github.com/wang-zidu/3DDFA-V3

3DDFA_V3 uses the geometric guidance of facial part segmentation for face reconstruction, improving the alignment of reconstructed facial features with the original image and excelling at capturing extreme expressions. The key idea is to transform the target and prediction into semantic point sets, optimizing the distribution of point sets to ensure that the reconstructed regions and the target share the same geometry.
