Soft-Copy and Palette-Color Extension for Color Facsimile Standards
  DOI :  10.2352/CIC.1995.3.1.art00046  Published OnlineJanuary 1995

In the last several years, tremendous progress has been made toward the development of international standards for Color Facsimile within the International Telecommunication Union—Telecommunication Standard Sector, ITU-T (formerly called the CCITT). The first goal of these efforts is to encode and communicate full-color continuous-tone images using the JPEG image compression standard and the CIELAB color space as the color interchange space. For this goal, ITU-T Recommendation T.42 “Continuous-tone colour representation method for facsimile” and new annexes and revised recommendations for Group 3 and Group 4 facsimiles were developed and approved by ITU-T in 1994. The next goals of these efforts are soft-copy and palletized color image extensions for color facsimile. For soft-copy facsimile, color interchange space and optional color reproduction information are being proposed at ITU-T. For encoding palletized color images and lossless continuous-tone images, the JBIG image compression method is being considered by ITU-T. The recent progress in the above proposals are reported in this paper.
