Abstract

SNR expressions are derived for four different correlators in which, respectively, (1) the input and template are gray-scale signals, (2) the template signal is binarized, (3) the input is binarized, and (4) both signals are binarized. These expressions can be used with any reference image to quantify the loss of SNR due to binarization. The present results indicate that SNR loss due to binarization is not severe, allowing a relaxation of linearity and dynamic range requirements.
