Abstract
A two-dimensional image is subjected to a three-dimensional effect, such as folding, twisting or rotation, and transformed or warped into a modified output image. By successive one-dimensional resampling along two coordinates and parallel channel processing of transposed input image data with rejection of distorted pixel value data, bottleneck, shear and other distortions are addressed. Complete warping systems, resampling subsystems and related methods are disclosed.
