Enhancement of Group 4 Facsimile to Include Color Imagery

摘要

The purpose of this study is to investigate and analyze alternative technique forthe communication of color facsimile. There are two broad objectives; develop a detailed recommended standardized approach for binary color facsimile, and investigate the potential standardization for dither/half-tone and continuous tone color facsimile. With the advent of low-cost color scanners and color pictures, color facsimile is fast becoming a reality. Some color facsimile equipment are already appearing in the marketplace. There are no standards available from the CCITT or other standards groups which might ensure the interoperability of different manufacturer's equipment, although standards bodies are beginning to discuss color.
