Abstract

 Abstract— The proposed paper aims in developing an efficient block classification using histogram for compressing compound images that contain graphics, text and picture images. In this paper, the given compound image is segmented into 8x8 blocks and these blocks are used for the image classification. The segmented blocks are classified into blocks of four different types: background blocks, text blocks, mixed blocks and picture blocks. The efficiency of block classification is observed to be of 97% for compound and computer generated images. The proposed block classification method is very simple and effective in compressing compound images. This paper discuss about the block classification of compound images using MATLAB.
