DCT-based JPEG Image Compression and Implementation
WU Shu-lu · Journal of Qinghai Normal University · 2010
For images,if necessary for fast or real-time transmission,it has to compress the image,but with the development of the network,image compression technology has been growing concern.DCT transform is an important technology for image compression.In this paper,I did a lot research on DCT-based JPEG image compression along with the Matlab simulation.The method is simple,fast and error is small,which greatly improves the efficiency of image compression.
