The motion is estimated by computing the components of the structure tensor from which normal flows are extracted. By projecting the 3D spatiotemporal data to 2-D planes we obtain projection coefficients which we use to evaluate the 3-D orientations of brightness patterns in TV like 2D image sequences. This corresponds to the solutions of simple matrix eigenvalue problems in 2D, affording increased computational efficiency. An implementation based on joint lip movements and speech is presented along with experiments which confirm the theory, exhibiting a recognition rate of 98% on the publicly available XM2VTS database.</p> Conference on Computer Vision and Pattern Recognition Workshop, New York City, New York, 17-22 June, 2006 http://dx.doi.org/10.1109/CVPRW.2006.158 http://hh.diva-portal.org/smash/record.jsf?searchId=1&pid=diva2:239668 37 Conference on Computer Vision and Pattern Recognition Workshop : New York City, New York, 17-22 June, 2006 Conference Paper 37 Person verification by lip-motion 2006 2016-09-30T20:40:52Z 2457662.361713 Person verification by lip-motion 500 0 plainlist list 1 [[:Publications:Person verification by lip-motion]] Person verification by lip-motion# QUERY1e74dac3b6760df3eec5af44c8a5d25a 500 [2,"smw-datavalue-property-restricted-annotation-use","Publisher"] Person verification by lip-motion# ERR6c155b5d70b69ddb590b4f2e73389c2a 500 [2,"smw-datavalue-property-restricted-annotation-use","Author"] Person verification by lip-motion# ERRe24f17e090c98448f3de99d03182b7b6
