摘要

in this hybrid model we proposed Hybrid technique combination of sundry compression techniques. Image compression is reduce the number of bits required to represent an image without degrading the quality of the image to an unacceptable level. The reduction in file size allows more images to be stored in a given amount of disk or memory space and reduces the time required for images to be sent via the Internet. Storage capacity and the speed of transmission are the two important factors that arise during the heavy duty of multimedia over Internet. The best image quality at a given bit-rate (or compression rate) is the main goal of image compression. we implement lossless technique so our PSNR and MSE will go better than the old algorithms and due to DCT and DWT we will get good level of compression. Hence overall result of hybrid compression technique is good.
