Abstract
In image matching applications such as tracking and stereo matching, it is common to use the sum-of-squared- diflerences (SSD) measure to determine the best match for an image template. However, this measure is sensitive to outliers and is not robust to template variations. We de- scribe a robust measure and eficient search strategy for template matching with a binary or greyscale template us- ing a maximum-likelihood formulation. In addition to sub- pixel localization and uncertainty estimation, these tech- niques allow optimal feature selection based on minimizing the localization uncertainty. We examine the use of these techniques for object recognition, stereo matching, feature selection, and tracking.
