A Design and Implementation of Orthonormal Symmetric Wavelet Transform Using PRCC Filter Banks

By Adiga Abhijin, KR Ramakrishnan and BS Adiga


We propose a framework for orthonormal symmetric wavelet transform given a cyclic zero-phase half band filter. The scheme consists of a design for cyclic wavelet transform with real symmetric filters based on the Perfect Reconstruction Circular Convolution Filter Banks accompanied by an implementation in the Discrete Trigonometric Transform domain. This is followed by a brief discussion on its performance in the context of applications such as image compression and implementation of symmetric wavelet transforms based on bandlimited wavelets
