Abstract (en)

[origin: WO2006061365A1] 3D object data is represented by determining a point-of-interest (poi) in a predetermined position relative to the object, and generating for that point-of- interest (poi) a set of multiple isoradius surface contours (IRAD), each of which comprises a locus of a set of points (p1, p2, p3) on the surface of the object that are at a constant predetermined distance from the point-of-interest (poi), which distance is different for each contour of the set. A plurality of properties, such as curvature and colour / intensity, can be taken along each contour, to provide a series of aligned 1D signals that can be used for object recognition or verification. This may find particular application to the recognition or verification of human faces.
