Paper Abstract

This paper presents the Local Cosine Transform as a new method for the reduction and smoothing of the blocking effect that appears at low bit rates in image coding algorithms based on the Discrete Cosine Transform. In particular, the blocking effect appears in the JPEG baseline sequential algorithm.
