Optimumization of lifting structure of reversible KLT based on permutation of signal's order and sign

Abstract

This paper proposes a “reversible” three-point Karhunen Loeve transform (KLT) for de-correlation of RGB color components of an image signal. It is composed of “reversible” two point rotation transforms which have singular points (SP) and their rotation angles change depending on correlation of an input signal. When the angle is… (More)
