Image compression using multiple transforms

Discrete cosine transform (DCT) is used in practically all commercial image and video compression systems. It has been found to be the best choice among all unitary transforms in compressing natural images. We are also quite convinced that it is difficult to find any clear alternative for DCT in typ...
