Framelets with Three Generator by Unitary Extension Principle
Kanchan Lata Gupta · International Journal of Advanced Trends in Computer Science and Engineering · 2020
In this paper we have given a straight forward method to generate compactly supported tight wavelet frames (framelets) for a scaling function based on unitary extension principle (UEP).Here we decompose the refinement mask into polyphase form and then apply UEP.Example are discussed for framelets generated from cardinal B-spline of different order.
