The new image encoding algorithm based on analyzing the characteristics of the wavelet transform and the disadvantages of the EZW is presented.The main content is position matrix is set to record the location of wavelet coefficients,scanning the important wavelet coefficients first by using ordered quad-tree,and encoding the sign by using run length coding as well.Theoretical analysis and experimental results show that this algorithm has not only quicken encoding,but also improve the quality of… CONTINUE READING
