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. Although JPM allows the use of JPEG 2000, access into a JPM file is limited by the access features of the older coders used. JPEG 2000 is an image coding system that allows access to lower resolutions, progressive bit-rates, and regions of interest. This paper describes methods for using JPEG 2000 in conjunction with older binary coders in a JPM file. Using these techniques it is possible to get close to the best rate-distortion performance and have access into the file.
