  • Automatic planar point pattern matching device and the matching method thereof
    Patent number: 5392367
    Abstract: Matching probability among planar point patterns is calculated by a mating probability calculating device to decide the corresponding relationship therebetween and the best point matching is then selected by a mating point selecting device. The similarity therebetween is computed by a similarity calculating device to decide correct the results of pattern matching. An algorithm associated with the devices is also provided.
