Paper Abstract

The process of color image reproduction from scanners to printers includes a series of steps. For realizing color reproduction, artificial neutral networks are used to each of steps separately or the whole process. However, In applications, these technologies are still complex. For convenience to applications, this paper presents a simple method of color image reproduction from scanner to printer and color prediction before printed using a back-propagation neutral network, which maps RGB values between scanner and printer directly and teacher values can be gotten automatically. The processes of color production and color prediction use the same network structures, same leaming data and inverse learning method. Experimental results show that, using this method of color reproduction average color difference ?Eab between the print-out image and scan-in image are reduced from 15 to 4 units. The network has better behave for color prediction than color reproduction, and the reason is discussed.
