Color Picture Processing By Computer

This paper introduces a computer cystem for color picyure processing and its principal features. First the hardware aspectB are explained, including the basic characteristics of I/O devices. The interactive feature of our system is singled out, and it is developed to a system concept called "Color Picture Analysis and Display System" The color analysis method and its software are presented and discussed, since the correct recognition of color information is important in color picture processing. This paper slso contains some methods and applications of effective use of color information in picture processing. They include (1) domain identification by color information (2) color effect method (3) color separation (4) conversational re-touching of color (5) pseudo-color displaying and their applications. 1. Introduction Picture processing by computer has been of considerable interest in computer science and robotics research. Most efforts in picture processing have been concerned with monochromatic pictures* But, as everyone realizes, actual scenes and pictures all contain color, and color information plays important roles in human perception and recognition of scenes and pictures. This suggests the usefulness of color information in picture processing by computer. In Ito(1973) we have discussed some basic problems and a conceptual framework for color picture processing by computer. We stated there the need of an experimental computer system for color picture processing and emphasized the importance of "com-puter-oriented chromatics". This paper contains an overall description
