(1. 河南科技大学电子信息工程学院,河南洛阳 471003 2. 中航一集团洛阳电光设备研究所,河南洛阳 471009)-introduced the JPEG image compression algorithm, MATLAB and mathematical analysis tool environment from experimental perspective, more directly on the DCT in JPEG image compression applications. Simulation results show that the use MATLAB to achieve discrete cosine transform image compression method is simple, fast, the advantages of a small error, which has greatly enhanced the efficiency of image compression and accuracy.
