Abstract
Combined with highly efficient SPIHT algorithm, an arbitrary shape integer or non-integer wavelet transform is employed to implement the lossless compression of region of interest (ROI) with arbitrary shape and lossy compression of non-ROI. Further, two strategies of ROI coding with priority are proposed to guarantee that the reconstructed image of ROI can achieve more better visual quality that non-ROI even at very low bit rate, which will satisfy the quick and individual browse requirement of users. The compressed bitstreams are all embedded and suitable for progressive transform.
