Accuracy Improvement Method for Pixel-Selection Template Matching for Small-Scale FPGAs

Abstract

We propose a method to enhance accuracy by improving the pixel selection method in the circuit configuration of template matching using limited pixels. By selecting a pair of pixels with a low co-occurrence probability or a large difference in pixel value from the left and right pixels at a certain distance from the pixel selected based on image features, matching accuracy can be improved while using the same circuit as the conventional one.
