摘要：The new image compression standard JPEG2000, provides high compression rates for the same visual quality for gray and color images than JPEG. JPEG2000 is being adopted for image compression and transmission in mobile phones, PDA and computers. An image may contain the formatted text and graphics data. 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. This method can be easily adapted in image compression applications without changing the syntax of compressed stream.
