A DISCRETE WAVELET TRANSFORM - SINGULAR VALUE DECOMPOSITION SYSTEM FOR IMAGE CODING

A system that combines techniques of wavelet transform (DWT) and singular value decomposition (SVD) to encode images is presented. The image is divided into tiles or blocks of 64x64 pixels. The decision criterion as to which transform to use is based on the standard deviation of the 8x8 pixel subblo...
