Lossy to lossless image compression based on reversible integer DCT
A progressive image compression scheme is investigated using reversible integer discrete cosine transform (RDCT) which is derived from the matrix factorization theory. Previous te...

Subband Image Coding Using Cosine Modulated Filter Banks with Perfect Reconstruction and Linear Phase
lye propose a lossy image coding scheme based on the recently introduced even-stacked cosine modulated filter banks (CSIFBs) that allow linear phase filters in all channels. We des...
