<p>Area correlation of images or regions of images may be used directly to measure field distortion such as rotation, expansion, or shear, once translation disparities are removed between a pair of images. A method is disclosed for allowing relative field distortions to be applied between a pair of image regions as they are correlated. In binocular stereo, the method enables measurement of elevation gradients and surface curvatures. In motion analysis, the method enables the direct measurement of flow field parameters, while in template matching, rotation and magnification may be measured without the necessity of multiple templates for the same object.</p> |
