摘　　要：对于图像来说,如果需要进行快速或实时传输,就要对图像进行压缩,而随着网络的发展,图像压缩技术越来越被人们所关注.DCT变换是图像压缩的一项重要技术.本文主要对基于DCT变换的JPEG图像压缩进行研究,并用Matlab进行了算法仿真.其方法简单、速度快且误差小,大大提高了图像压缩的效率.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.
