Abstract

A matrix method is considered to construct simple order-32 integer cosine step transform. A one-norm simple order-32 integer transform is proposed and its fast algorithms are developed whose computational complexity is 4.3 times smaller than that of well-known algorithms and 19 times smaller than that of the H.265 standard.
