ABSTRACT:
A pattern matching system includes a circuit that matches an input image with a template based on a correlation function. The circuit has a structure which makes it particularly suitable for implementation in Large Scale Integration (LSI) technologies. A pattern matching circuit according to this invention sets up a threshold value of a correlation coefficient and evaluates the following formula,
