Abstract
A method of finding unique targets arranged in a unique sequence of targets in a color image applies ratio space rich colored filtering to identify a band of pixels that form a transition curve from one rich color to another. A set of transition curves with simple geometric and color properties for the entire image, are compared to a database of target properties to identify a target in an image. The targets are provided on a carrier that is attached to a surface to enable processor to identify the surface location and orientation by the targets.
