Abstract

The design and development of binarized composite binary phase only filters for three-dimensional image identification is discussed in this paper. A composite binary phase only filter based algorithm is developed to detect an unknown image from the pre-constructed database. The angular position of the unknown image is found by a cross correlation technique. The formulation of composite filters reduces the number of correlation operations necessary for detection.
