Abstract: A new video compression coding method based on Surfacelet transform and SPIHT algorithm was proposed.The new method treats the video signal in a special 3D signal with space and time axes in a whole.Surfacelet transform achives properties of multi-directional decomposition,anisotropy,efficient tree-structured implementation,refinable angular resolution,low redundancy and so on.SPIHT algorithm is scalable and progressive in resolution.The video data compression coding is completed by using the properties of correlation and energy concentration between layers of decomposing factors in Surfacelet transform and SPIHT algorithm.The new video compression coding method can overcome the shortcoming of the method based on 3D wavelet transform,achiving higher PSNR and better vision effect,especially for video with complex texture and small motion.
