Summary: 
This paper describes an efficient PCRD (Post-Compression Rate-Distortion) scheme for rate control of JPEG2000. The proposed method determines the rate constant in consideration of the decreasing characteristic of RD-slopes and conducts rate allocation about only coding passes excluded from the previous rate allocation. As a result, it can considerably reduce the number of operations and encoding time with nearly the same PSNR performance as the conventional rate control scheme of JPEG2000.
