Abstract
Many image data are usually archived and transmitted in the compressed form[1], for example, JPEG. Traditionally, manipulating the JPEG image must fully decompress first. Because the traditional method is not efficient, it can not satisfy the requirements of real-time system, so, studying the technology of image processing based on DCT compressed domain is urgent. This paper describes the JPEG compressed algorithm, the method of DCT compressed domain image processing and the location of the image processing in DCT compressed domain.
