Abstract : The purpose of this project was to continue the work on color facsimile that was started in 1994. This report describes the creation and evaluation of default Huffman codes, which were completed in the last year. The development of default Huffman codes was a continuation of work performed in 1994. The modified Joint Photographic Experts Group (JPEG) software developed last year was used to compress images from two different classes. Newly developed software was then used on the resulting histograms to create composite Huffman code tables for the two images classes which could be used as defaults. This report is comprised of two section: (1) provides a brief description of the objectives of the task and an outline of the contents of this report; and, (2) describes the creation and performance of default Huffman coding tables for transmitting color FAX images by the JPEG (Joint Photographic Experts Group) baseline standard.
