Abstract
Concerning that the conventional color image coding algorithm does not take advantage of the dependency of the RGB color components,a new algorithm of set-partitioning RGB color components synchronously based on the Set Partitioning In Hierarchical Trees(SPIHT) algorithm was proposed.In this algorithm,RGB color components were treated as a whole,partition was sorted and set at the same time by using the same list of LIS.The color embedded bit-stream generated by this algorithm can stop at any point of the bit-stream and reconstruct the color image.The simulation results show the Peak Signal-to-Noise Ratio(PSNR) of the new algorithm on test images is about 0.1dB to 0.70 dB higher than JPEG2000's.
