Along with the rapid development of multimedia technology, still images used more widely. It mainly concentrated in the application of image storage and image transmission from two aspects, the concrete application we can see still images occupied more and more resources. In this background conditions, static image compression became a research hotspot.

JPEG is a kind of using forecast coding (DPCM), discrete cosine transform (DCT) and entropy coding, to remove redundant image and color data lossy compression formats, can the image compression in small storage space, the image of repeated or not important information will be lost, so easy to cause the image data of damage. Especially with high compression ratio, will make the final solution compress recovery after image quality decreased obviously, if pursue high quality image, unfavorable use high compression ratio. But JPEG compress technique is very advanced, it USES lossy compression mode to remove redundant image data in obtaining high compression rate at the same time can show very vivid image, i.e., can with the least amount of disk space to get a better image quality. And JPEG is a kind of very flexible format, which can adjust the function that allows image quality with different compression ratio on files compressed, supports multiple compression levels, compression ratio between now to usually in chains, compression ratio, the greater the character is lower; Conversely, the smaller the compression ratio, quality is better.
