An image compression method for video decoding based on a motion compensation such as MPEG-2 by using an image compression algorithm in which an image characteristic is differentiated on the basis of a difference between adjacent pels and finally classified by image types by using image characteristic information, and a suitable code word is assigned to each image type, thereby executing an image compression. There is also provided a CDC (classified differential coding) algorithm that defines a bundle by setting up a size of a pel block and searches the values between the adjacent and neighboring pels and its variation pattern, by which the computational complexity is reduced for the image compression coding, while satisfying the random accessibility of the memory. |
