In methods, systems, and computer program products for locating a regularly configured object within a digital image, a plurality of primary rotated integral images of the digital image are computed. Each primary rotated integral image has a different in-plane rotation. A set of secondary rotated integral...http://www.google.fr/patents/US7274832?utm_source=gb-gplus-shareBrevet US7274832 - In-plane rotation invariant object detection in digitized images
