Abstract

A novel rate control scheme using successive bit-plane rate allocation (SBRA) is proposed for JPEG2000 image coding. By using the current rate-distortion information only, the proposed method can achieve a quality close to the post-compression rate-distortion (PCRD) optimization scheme adopted in JPEG2000. The proposed scheme can efficiently reduce both the computational cost and working memory size of the entropy coding process up to about 90%, in the case of 0.25bpp (1/32) compression. Without using the future rate-distortion information, the sequential property of the proposed method is highly suitable for real-time (or low delay) applications and implementation.
