Abstract
In this paper a wavelet and region-based image compression scheme was proposed. The wavelet coefficients at each level related to a square or circular interested regions were accurately located. Methods of combining localization of wavelets with weighting factors are presented. This approach overcomes the difficulty arising from JPEG and exhibits the ability to allow users to construct the region of interest with PSNR scalability in a compressed image.
