Improvement of SPIHT Algorithm

In order to enhance the working efficiency of SPIHT algorithm, to reduce its complexity, to implement it easily in the software and hardware, an improvement to the original SPIHT algorithm has been made through adjusting sorting process of wavelet coefficients, substituting for the original chain table structure with one dimensional array, changing important judgment basis of wavelet coefficients. The results of experiments indicate the complexity of the algorithm was reduced and storage space was saved as well.
