Abstract:
A method for image representation such as segmentation using compressed image data, wherein an image is represented as a pixel value provided at each pixel in an image plane which is divided into a plurality of blocks, and said compressed data include at least position data of a similar region about each of said blocks, comprising:a) a step of setting mapping points at positions over two pixels which are represented by coordinates of said image plane;b) a step of performing a map in which each of mapping points moves from a block including said mapping point to a corresponding position in the similar region, wherein each of said mapping points is directly representative of a position of a pixel;c) a step of repeating said map;d) a step of clustering a plurality of mapping points, wherein mapping points in a first cluster are positioned near one another; ande) a step of adding a first pixel value to pixels in the first cluster of mapping points, and adding different pixel values, different from the first pixel value, to pixels in different clusters, different from the first cluster.
