- W789917829 abstract "We show how to actively compute local qualitative shape properties directly from image intensities, that is, without having to first reconstruct the surface. Our approach differs from classical active shape-from-shading (photometric stereo, Woodham, 1980), in two ways. First, we do not attempt to compute a dense depth map of the surface. Instead, we detect the presence of certain local qualitative geometric features. Second, we use two different types of lighting conditions rather than two different instances of a single type. Our two types of lighting conditions are a diffuse source and a point source positioned at the camera. The major result of this paper is that surface concavities such as orientation discontinuities and smooth valleys typically share the same shading signatures. Under diffuse conditions, both produce local minima in the image intensity; under the point source condition, both produce local maxima in the image intensity. These 1-D features may be detected, although not discriminated, by alternating between the two lighting conditions." @default.
