Abstract

This paper proposes use of the hybrid JPEG/recursive block coding (JPEG/RBC) algorithm in low bit rate image coding and presents a quantization matrix (QM) design for the DST blocks that can be used for a wide range of low DST bit rates. The data rate optimization problem encountered in the JPEG/RBC algorithm is discussed and an empirical ratio of the bit rates for the DCT and the DST blocks is obtained for low bit rate image coding. Subjective evaluation of images coded at low bit rates placed JPEG/RBC in the top group of three algorithms among those submitted for possible inclusion as the next generation bandwidth compression algorithm in the National Imagery Transmission Format Standard.
