Abstract
Joint transform correlator (JTC) is a well known tool for color pattern
recognition for a color image. Color images have red, green and blue components,
thus in conventional JTC, three input channels of these color components are
necessary for color pattern recognition. This paper proposes a new technique of
color pattern recognition by decomposing the color image into three color components
and recombining those components into a single gray image in the input plane. This
new technique needs single input channel and single output CCD camera, thus a simple
JTC can be used. We present various kinds of simulated results to show that our
newly proposed technique can accurately recognize and discriminate color
differences.
