Abstract

The discrete W transform (DWT), introduced by Wang Z, has been used in many applications of digital signal processing, data compression and information hiding. The unified form of discrete W transform has two parameters. There are four useful types of the discrete W transform. In simulating the discrete W transform, we propose a generalized discrete W transform with three parameters, and prove its orthogonality for some new cases.
