A fast multi-resolution template search method (106) uses a manually selected or an automatically selected (102) template set, learned application specific variability (530, 532), and optimized image pre-processing to provide robust, accurate and fast alignment without fiducial marking. Template search is directed from low resolution and large area into high resolution and smaller area with each level of the multi-resolution image representation having its own automatically selected template location and pre-processing method. Measures of discrimination power for template selection and image pre-processing selection increase signal to noise and consistency during template search. Signal enhancement means (801) for directing discrimination of optimum template location are taught. |
