Sequential scene matching with hierarchical search
Abstract
A technique is developed for scene matching by computer. It is more efficient than methods currently in use as less computations are required. The technique employs a hierarchical search for a potential match location beginning at the lowest possible resolution. At each level of resolution sequential testing and detection methods are utilized, resulting in reduced computations. The method is applied to matching image regions greatly corrupted by noise; experimental results are presented. It is suggested that the proposed technique may be used in cases not applicable to humans or standard correlation techniques.
