Color Imaging with JPEG 2000

摘要

The JPEG 2000 image compression standard is a wavelet-based follow-on to JPEG. While it offers better compression performance, JPEG 2000 is not expected to replace JPEG. What it is expected to do is to offer new features and capabilities, so that an encoder/decoder (client/server) will have processing choices not possible with previous compression methods. This is expected to lead to unique color imaging applications for the Web, digital cameras and handheld devices. Part 1 of the JPEG 2000 standard defines the minimal decoder and was approved as an international standard in January 2001. Still in the standards pipeline are several more parts that will specify decoder extensions, file formats, conformance and reference software. This paper will give the background and an overview of JPEG 2000, demonstrate its performance and then describe its implications for color imaging.
