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 uniļ¬cation of lossless and lossy image coding, called losslessto-lossy image coding. In this paper, we...

Systematic construction of real lapped tight frame transforms
Abstract--We present a constructive algorithm for the design of real lapped equal-norm tight frame transforms. These transforms can be efficiently implemented through filter banks ...

Image Coding Using Vector-Embedded Karhunen-Loeve Transform
In this paper, the theory and the design of a new class of orthogonal transforms are presented. The novel transform is derived from a correlation matrix in which an arbitrary orth...
