Abstract:
Compound document images are usually high resolution and high quality images that include color, graphics, and images in addition to text. The need for good compression is important for storage and transmission. Due to the large size, even compressed, it is often difficult to access document images quickly and efficiently for display on monitors. The nascent JPM file format enables the best compound document image compression in terms of rate-distortion. However, the access into a JPM file is limited by the access features of the coders used. JPEG 2000 is an image coding system that allows access to lower resolutions, progressive bit-rates, and regions of interest.
