Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Computers and Information - Department of Information Technology Summary: This thesis proposed two techniques for near-lossless image compression both of them are aiming to improve the compression ratio. The first one is based on vector quantizer with constrained error and the second one based on wavelet and histogram packing. In the first technique, There are two stages of Constrained Vector Quantizer (CVQ) are used, in the first stage the input image are quantized but under constrain that is no pixel error should excced a certain error VQ error
