主　　题：medical image integer wavelet transform differential plus code modulation(DPCM) lossless compression 

摘      要：To improve the classical lossless compression of low efficiency,a method of image lossless compression with high efficiency is *** theory and the algorithm implementation are *** basic approach of medical image lossless compression is then briefly *** analyzing and implementing differential plus code modulation(DPCM)in lossless compression,a new method of combining an integer wavelet transform with DPCM to compress medical images is *** analysis and simulation results show that this new method is simpler and ***,it has high compression ratio in medical image lossless compression.
