Shape From Shading
Shape From Shading is the process of computing the threedimensional shape of a surface from one image of that surface. Contrary to most of the other three-dimensional reconstruction problems (for example, stereo and photometric stereo), in the Shape From Shading problem, data are minimal (we use a single image!). As a consequence, this inverse problem is intrinsically a difficult one. In this c...
متن کاملPerceiving shape from shading.
Our visual experience of the world is based on two-dimensional images: nat patterns of varying light intensity and color faIling on a single plane of cells in the retina. Yet we come to perceive solidity and depth. We can do this because a number of cues about depth are available in the retinal image: shading, perspective, occlusion of one object by another and stereoscopic disparity. In some m...

direction of the camera, the local shape recovered assuming the extremum is a minimum is the reflection of the A global shape from shading algorithm which develops a technique to merge local shape from shading results obtained shape recovered assuming the extremum is a maximum, around singular points into the complete shape using the mounand therefore the same saddle point will be found. This t...
متن کاملRobust Shape from Shading
Existing Shape from Shading algorithms are not robust enough to work reliably with real images. We present a new paradigm for Shape from Shading based upon & scale space surface representation. Using this representation, the Shape from Shading problem becomes one of forming a surface from gaussian basis functions in such a way that the shading in the original image is explained. The algorithm i...
متن کاملShape from Shading through Shape Evolution
In this paper, we address the shape-from-shading problem by training deep networks with synthetic images. Unlike conventional approaches that combine deep learning and synthetic imagery, we propose an approach that does not need any external shape dataset to render synthetic images. Our approach consists of two synergistic processes: the evolution of complex shapes from simple primitives, and t...
