Multidimensional Fast Multiplierless DCT Algorithm Using Ramanujan Ordered Numbers

Abstract

—This paper proposes a new multidimensional (m-D) multiplierless Ramanujan Numbered Discrete Cosine Transform (RDCT) based coding to improvise the coding efficiency in the visual data compression for multimedia applications. In this paper, the mD-DCT with size 12 m N N N   , where i N power of 2 is, can be converted into a series of one dimensional (1-D… (More)
