Abstract
Image compression by the warped stretch transform is introduced, where the input image is reshaped by a signal-dependent mapping i.e. designed “warp kernel”. The warped image can be downsampled at a lower uniform rate for the same PSNR, effectively achieving reversible and context-aware non-uniform sampling.
