Abstract

JPEG has recently been recognized as the most popular and effective coding scheme for still-frame, continuous-tone images. At a moderate bit rate, JPEG can usually give a quite satisfactory solution to most of practical coding applications. However, the blocking effect produced by JPEG tends to be rather disturbing when a higher compression rate is required. In this paper, we propose a novel interpolative coding scheme which is based on the JPEG technology. As compared to the standard JPEG, the efficiency of this interpolative scheme is enhanced and, more importantly, the blocking artifacts have been reduced significantly, thus yielding a much more pleasant visual result.
