Disclosed is an apparatus, method, and computer program product for ridge map formation. The method for processing an image data structure to extract a feature defined by a plurality of contiguous data elements includes identifying a set of candidate image feature pixels, the set including one or more pixels from the image data structure; examining local image data surrounding one or more pixels of the set of candidate image feature pixels to identify a set of potential image feature pixels with each of the potential image feature pixels having a characteristic consistent with being associated with the feature; and identifying the feature in the image data using the set of potential image feature pixels by locating one or more of the plurality of contiguous data elements neighboring one or more pixels of the set of potential image feature pixels. The computer program product includes instructions executable by a processing unit, and those instructions perform the feature extraction as described herein. The system is an apparatus for processing an image data structure to extract a feature defined by a plurality of contiguous data elements.
