Near-Lossless Medical Image Compression Based on Lossless Regions of Interest(ROI)
Ma Dai · Computer Knowledge and Technology · 2007
A new algorithm with lossless regions of interest is present based on the Integer Wavelet Transform (IWT) and SPIHT scheme. One 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. The compressed bitstreams are all embedded and suitable for progressive transform.
