ABSTRACT:
A point pattern matching method and system for use in an object recognizing system for deciding pair combinations between a first group of n points x.sub.j (n: integer of 2 or more) (j: integer between 1 and n) in a K-dimensional space (K: integer of 2 or more) and a second group of n second points x.sub.i (i: integer between 1 and n) in the same space as the K-dimensional space. A total of n.sup.2 of neurons are provided one for each one of point pair combinations between the first group of points and the second group of points, and, when an output of each of the neurons has a value of substantially "1", it is determined that the point pair combination associated with the neuron is matched, whereas, when the output of the neuron has a value of substantially "0", it is determined that the point pair combination associated with the neuron is not matched.
