Color character recognition method based on human perception

摘要

Color is one of the most powerful and important types of visual information in various fields such as image processing, electronic imaging, and robot vision technologies. A new color character recognition system, composed of a camera, optical filters, an image board, a neuro board, and a micro computer was constructed. Using typewriter characters and backgrounds in five colors, two kinds of experiments were performed. The first consisted of preliminary experiments testing the effectiveness ofthe modified opponent-colortheory ofthe human eye for use in machine character recognition. The second was an experiment in color character recognition, in which the system recognized both characters and their colors.
