ABSTRACT:
An improved machine vision apparatus, of the type having a search element capable of estimating the location of a template image in a candidate image, includes an element that accepts signals representative of the template and of a candidate image. Those signals are applied to the search element to obtain its estimate of location. A correction element responds to the resulting approximation by the location-finder for generating a signal representative of more exacting location based on a known relationship between the location-finder output and more exacting locations of the template in a model of the candidate image.
