Abstract
Four key issues in wavelet zero-tree based image coding are investigates and presented, there are (1) Fast wavelet transform that save 1/2 and 3/4 processing for 1D signal and 2D signals respectively. (2) The selection of the best wavelet filters that yields best performance (PSNR vs. Bit rate) for most common seen images. (3) Recommendation of number of wavelet scales (or frequencies) for image coding by experiments and analysis.
