Abstract :
It is shown that the statistical properties of the mean absolute difference mismatch measure surface is dependent on the autocorrelation function of image and signal-to-noise ratio. A method for finding the match point is presented, based on the idea of testing a set of hypotheses. Using the threshold estimation formulas and the optimized search scheme developed by the authors, a fast algorithm which may be adaptable to various expected operating conditions can be implemented
