Abstract

We propose a fast and reliable method for object detection using color and intensity information. The probability of hue and pixel values (gray level intensity values) in two-pixel pairs occurring in a template image is calculated, and only those pixel pairs with extremely low probability are carefully selected for matching. Since these pixels are highly distinctive, reliable matching is not affected by surrounding disturbances, and since only a very small number of pixels is used, the matching speed is high. Moreover, the use of the two measures enables reliable matching regardless of an object’s color. In a real image experiment, we achieved a recognition rate of 98% and a processing time of 80 msec using only 5% (684 pixels) of the template image. When only 0.5% (68 pixels) of the template image was used, the recognition rate was 80% and the processing time was 5.9 msec.
