IMAGE PROCESSING SYSTEM AND METHODS FOR ALIGNING SKIN FEATURES FOR EARLY SKIN CANCER DETECTION

摘要

Image processing system and methods for aligning features suitable for use in early skin-cancer detection systems Corresponding skin features between a reference image and a later captured image are precisely aligned Curvatures are used to align body outlines of corresponding images using body-background masks An initial-displacement flow field map, generated from the aligned body outlines, may be applied to a filtered version of the later-captured image to generate a pre-warped image The pre-warped image the reference image are divided into a plurality of overlapping chips and a correlation is performed between corresponding chips A transformation map may be generated based on the chip correlations This chipping process may be iterated for successively smaller chip sizes to generate a final transform map which may be applied to the later captured image to generate a registered image having its skin feature aligned with the reference image.
