Advanced JPEG 2000 Image Processing Techniques

摘要

JPEG 2000 is the emerging image compression standard. The base standard (Part 1) was approved in January 2001. Several corporations, research organizations, and individual parties are already offering software implementations of, at minimum, Part 1 of the specification. Some of the more commonly used features and benefits of using JPEG 2000 over JPEG are; superior image quality at low bit rates, image tiling, and lossless and lossy compression utilizing the same core algorithm. In this paper, we discuss some of the more advanced techniques in utilizing the JPEG 2000 standard for image processing, such as; using rate-distortion slope threshold values to compress sets of images to relative "Image Quality" levels, using precinct partition dimension values as an alternative to (or in addition to) using image tiling for the processing of very large images, and different methods for using ROI (Region of Interest) processing and the various progression ordering modes to achieve one's image processing goals. Examples will be given and results will be provided.
