A SVD Based Scheme For Post Processing of DCT Coded Images
In block discrete cosine transform (DCT) based image compression, the blocking artifacts are the main cause of degradation, especially at higher compression ratio. In proposed scheme, monotone or edge blocks are identified by examining the DCT coefficients of the block itself. In the first algorithm...
