Abstract:
A method for fitting a plurality of candidate templates in correspondence with a gray-scale image, comprising:receiving gray-scale image information of an observed image; defining a window which bounds a neighborhood about a target area within said image; extracting gray-scale image information relating to said bounded neighborhood; extracting gray-scale information from said candidate templates; for all candidate templates, determining at least one looseness interval value by an application of a pre-defined looseness interval function f(x,t) where x is said extracted gray-scale image information and t is said extracted gray-scale information from said candidate template information; defining at least one looseness threshold &dgr; for each determined looseness interval value; comparing each of said looseness interval values to its respective looseness threshold &dgr; such that templates having a looseness value less than or equal to its respective looseness threshold &dgr; are identified as loosely fitting templates; designating any of the identified loosely fitting templates as a match; and fitting at least one of any of said Identified matching templates to said defined window of image data.
