Region of Interest Based Image Coding and Progressive Transmission
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.
