A Novel Technique for Compressing MRI Image Based on CROI

Many image compression techniques have been developed for compressing medical images. These compression algorithms produce high compression rate with affordable loss in important region of images. But here a CROI based hybrid technique for the compression of Magnetic Resonance Image is proposed, in which Contextual Listless SPIHT algorithm is used. In this paper, the CROI (important information) and the BG (low priority information) were separated .Then CROI is priority information) were separated .Then CROI is encoded separately with high bpp and the BG is encoded separately with low bpp. Finally, the two regions are merged for reconstructing the original image.
