摘要: A method and apparatus for two-pass image transformation, providing a general solution to execute arbitrary warping of an image. bicubic mesh is created, by splines or other suitable means, used create displacement tables X Y displacement. Alternatively, the can be generated directly. The represent movement each pixel from original location in source new destination One maps applied intermediate map resampled map. then By resampling, compensation altered points done automatically. In this manner, no inversion underlying equations functions required.
