Integer fast lapped orthogonal transform based on direct-lifting of dcts for lossless-to-lossy image coding
Integer lapped orthogonal transforms (LOTs) are vital technologies for the unification of lossless and lossy image coding, called losslessto-lossy image coding. In this paper, we...

Improved Chen-Smith image coder
An image compression system based on transform coding and zonal sampling is presented. It is based on the wellknown Chen-Smith coder, but with an improved technique for transform ...

The Variable-Length Generalized Lapped Biorthogonal Transform
This paper introduces a class of linear phase lapped biorthogonal transforms with basis functions of variable length VLGLBT. The transform can be characterized by a lattice which ...

M-Channel Multiple Description Coding With Two-Rate Coding and Staggered Quantization
A low complexity M-channel multiple description coding scheme is developed in this paper, in which each description carries one subset of the input with a higher bit rate and the r...
