Abstract
We present a rate allocation scheme that pre-computes optimal quantisation bucket sizes based on a mathematical model of wavelet transformed natural images prior entropy encoding. We combine the proposed scheme with the JPEG2000 embedded rate-allocator and find in our experiments that it is able to increase JPEG2000 encoding speed by a factor of two without loosing image quality
