Warped Discrete Cosine Transform-Based Low Bit-Rate Block Coding Using Image Downsampling
This paper presents warped discrete cosine transform (WDCT)-based low bit-rate block coding using image downsampling. While WDCT aims to improve the performance of conventional DCT by frequency warping, the WDCT has only been applicable to high bit-rate coding applications because of the overhead re...
