Efficient Integrated Coding for Compound Image
M. Sundaresan, E. Devika · 2012
The development of computer and network technologies, image with mixed text, graphics and natural picture are seen everywhere, such as captur ed screen, web page, scanned electronic documents, slides, posters, compound images applications of computer screen image transmission. It is used to reduce the amount of data required t o present the digital image and to improve the appear ance of an image to a human observer an extract quantitative information. To compress a compound image various types of lossy and lossless algorithms are used. This research work deals with the preprocessing, macroblock divisions, transformations, quantization, text block and non used to compress a compound image to produce a high compression ratio, less compression time and decompression time and high PSNR value than the existing method.
