参考 C# OpenCvSharp 部署MOWA#xff1a;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。 项目 代码
