Colour and gray-scale image representations using lossless coding scheme for facsimile

ITU-T T.43 SPANISH-1997 发布历史

This Recommendation defines colour and gray-scale image representation and their coding schemes in order to make it possible to interchange colour and gray-scale image data such as one bit per colour CMY(K) or RGB image, palettized colour image, and/or continuous-tone colour and gray-scale image, using lossless coding scheme over a facsimile communication service such as Group 3 or Group 4 facsimile. Its purpose is to specify representation and lossless coding schemes for three types of colour and gray-scale images. The first one is one bit per colour CMY(K) or RGB image. The second one is palettized colour image. The last one is continuous-tone colour and gray-scale image. This Recommendation, together with documents such as parts of Recommendations T.4 and T.30, or T.563, T.503 and T.521, will define a colour image data format that may be used by colour facsimile service and by other telematic services. In this Recommendation, the coding scheme specified in Recommendation T.82 (JBIG) is used for lossless encoding of these three types of colour and gray-scale images. Application of other coding schemes are for further study.
