SPIHT algorithm for color images based on multiwavelet

This paper proposes an improved color Set Partitioning in Hierarchical Trees (CSPIHT) algorithm based on multiwavelet. In the proposed image coding algorithm, color RGB image is converted into YCbCr format. Clearly, coding bit stream luminance Y plane is higher than Cb and Cr chrominance planes. The new spatial orientation tree structure is developed between channel planes based on SPIHT coding idea. Combination with mutltiwavelet coefficients, we embedded multiwavelet SPHIT coding for color images. The result shows that this coding method is Valid and performance is superior to SPHIT on 9/7 wavelet.
