![A New Perspective [on] Shape-from-Shading](https://www.sciweavers.org/files/imagecache/thumbnail/default/content.jpg "A New Perspective [on] Shape-from-Shading")
Shape-from-Shading (SfS) is a fundamental problem in Computer Vision. The vast majority of research in this field have assumed orthography as its projection model. This paper re-e...
