摘要

引入了扭曲拉伸变换的图像压缩，其中输入图像通过信号相关映射(即设计的“扭曲核”)进行重塑。对于相同的PSNR，可以以更低的均匀率对扭曲的图像进行下采样，有效地实现可逆和上下文感知的非均匀采样。

Optics-inspired context-aware image compression using warped stretch transform

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.
