The unified framework of the JPEG2000 architecture makes practical high quality real-time compression possible even in video mode. The Part 3 of the JPEG2000 standard, Motion JPEG2000, uses an intra-frame style for video compression which compresses video sequence frame by frame using the JPEG2000 core coding system. However, the compression performance of the JPEG2000 behaves poorly when compressing an image with low color depth such as Graphics images. In this paper, we propose a technique to distinguish the true color images from Graphics images and to compress Graphics images using a simplified JPEG2000 compression method that will improve the compression performance. The proposed method can be easily adapted in Motion JPEG2000 framework for video sequence compression without the need for compressed bit-stream syntax modification.
