Abstract-Most of the internet sites involve buffering of compound images and people expect them to be of enhanced quality and stature. In this paper, H.264/MPEG-4 AVC for compound image compression using histogram based block classification scheme is implemented to evaluate the performance of compound images to better know the importance of this scheme. In this method, conventional histogram is adopted and improves the block classification between background, text, hybrid and picture image areas. Different compression scheme is implemented for different types of classified blocks to improve the compression ratio to an optimal value. H.264 AVC using CABAC entropy coding is used to compress the hybrid blocks, on the other hand standard conventional algorithm such as run-length, wavelet coding and JPEG coding for background, text and picture blocks respectively. Experimental results show that the proposed scheme improves the compression ratio of compound image to larger extent but increases the coding complexity
