Abstract
Detection of distorted target images is a common problem in optical pattern recognition. Many distortion-invariant filter designs have been developed. However, while detecting the distorted target, the value of the distortion parameters is lost. We introduce a method of optical morphology that transforms rotated target objects into a single line of bright dots. The location of these lines indicates the location of a target and the angle indicates the rotation of the target. We use a set of complex filter images referred to as super images configured in a correlation filter bank to accomplish this form of morphological transformation. The mathematical characteristics of super images are discussed and examples of their usage are demonstrated numerically.
