C# OpenCvSharp 部署MOWA：多合一图像扭曲模型

说明

算法模型的paper名称是《MOWA: Multiple-in-One Image Warping Model》

ariv链接 https://arxiv.org/pdf/2404.10716 

效果

Stitched Image

翻译成中文意思是：拼接图像。效果图如下，可以看到输入原图的边界是不规则的，在经过模型推理之后输出的图的边界是规整了。

Rectified Wide-Angle Image

翻译成中文意思是：矫正广角图像。效果图如下，可以看到输入原图的左右上下边界是扭曲的，在经过模型推理之后输出的图的边界是规整了。

Unrolling Shutter Image

翻译成中文意思是：卷帘快门图像。效果图如下，可以看到输入原图的右边界是弯曲的，在经过模型推理之后输出的图的边界是规整了。

Rotated Image

翻译成中文意思是：旋转图像。效果图如下，可以看到输入原图是有明显倾斜的，在经过模型推理之后输出的图是摆正了。

Fisheye Image

翻译成中文意思是：鱼眼图像。效果图如下，可以看到输入原图里的建筑物有明显扭曲的，在经过模型推理之后输出的图里的建筑物是正直的了。
