Abstract :
A very fast, low complexity algorithm for resolution scalable and random access decoding is presented. The algorithm avoids the multiple passes of bit-plane coding for speed improvement. The decrease in dynamic ranges of wavelet coefficients magnitudes is efficiently coded. The hierarchical dynamic range coding naturally enables a resolution scalable representation of a wavelet transformed image.
