Abstract
A novel method of corner detection for multicolor pseudo-random encoded image is proposed. With this method, the unique window characteristics of pseudo-random array pattern is extended to multicolor images, and by using quadratic curve fitting to pixel gray level around the feature point and solving its extreme value, the sub-pixel location of corner in multicolor pseudo-random code can be implemented.
