Region of interest based image coding and progressive transmission
Zhuo Li, Lan Shen, Kin‐Man Lam · 2004
In this paper,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.
