Temporal aspects of stereoscopic slant estimation: an evaluation and extension of Howard and Kaneko's theory.

abstract：:We measured the three-dimensional shape and two-dimensional surface reflectance contributions to human recognition of faces across viewpoint. We first divided laser scans of human heads into their two- and three-dimensional components. Next, we created shape-normalized faces by morphing the two-dimensional surface ref...
