N2 - In this paper, we presented a novel wavelet packet image coding approach which provides the functionality of fine granular bitstream scalability. The proposed progressive wavelet packet image coding scheme consists of three parts, wavelet packet decomposition, a quadtree sorting procedure for classifying wavelet coefficients and universal trellis-coded quantization for quantizing the sorted coefficients. The image coding results, calculated in PSNR and images reconstructed by the decoding algorithm, are either comparable to or surpass previous results, due to the flexible representation ability of wavelet packet, the effective quadtree classifier and the improved granular fidelity of the UTCQ over scalar quantization.
