Optimized exclusive binary correlation measurement method, optimized exclusive binary measurement device, and program for executing the method

摘要

PROBLEM TO BE SOLVED: To execute an exclusive binarization correlation measurement in the method and program executing the method for optimized exclusive binarization correlation measurement, by setting an allowable error span for judging whether the magnitudes of a reference signal and a measured signal are equal or not, at an optimum value. SOLUTION: Pixel values of each image of the reference signal and the measured signal are compared and exclusively binarized according to whether or not the values of the reference signal and the measured signal are equal. For the basis of judging whether or not the values of the reference signal and the measured signal are equal, the allowable error span is determined. According to the relation among the reference signal, the measured signal and the allowable error span, the exclusive binarization is applied to the measured signal, and the correlation of the reference signal and the measured signal is measured.
