Abstract :
Summary form only given. Progressive display of images by using a image segmentation algorithm is proposed. The regions in a segmented image are represented by assigning to them the mean intensity of the original image within the region boundary. The segmentation algorithm that merges repeatedly two neighborhood regions that minimize the sum squared error and that makes regions grow bigger is used. At one stage of the merging process two kinds of information are lost: the mean intensity values of two merged regions and the region boundary. So they are coded at each stage till the region number is one. In the decoding process, while the region is being split the image is reconstructed progressively
