Numerical Shape from Shading and Occluding Contours in a Single View (opens in new tab)

Numerical Shape from Shading and Occluding Contours in a Single View Ikeuchi, Katsushi An iterative method of using occluding boundary information is proposed to compute surface slope from shading. We use a stereographic space rather than the more commonly used gradient space in order to express occluding boundary information. Further, we use "average" smoothness constraints rather than the more obvious "closed loop" smoothness constraints. We develop alternate constraints from the definitio...
