非仿射变换还有其他术语吗?

解决方案

您发布的所有示例图像都可以使用 Quadrilateral Distortion 来完成.虽然我不能肯定地说四边形扭曲将涵盖所有非仿射变换.

这里有一个在 C# 中不太好的实现的链接......它可以工作，但速度很慢.浏览维基百科，了解可用于此类计算的许多不同优化

Are there any classes, methods in the .NET library, or any algorithms in general, to perform non-affine transformations? (i.e. transformations that involve more than just rotation, scale, translation and shear)

Is there another term for non-affine transformations?

解决方案

All of the example images you posted can be done with a Quadrilateral Distortion. Though I cant say for certain that a quad distort will cover ALL non affine transforms.

Heres a link to a not so good implementation of it in C#... it works, but is slow. Poke around Wikipedia for the many different optimizations available for these kinds of calculations
