In this paper, we address the problem of finding depth from defocus in a fundamentally new way. Most previous methods have used an approximate model in which blurring is shift in...

A new approach is presented for 3D shape recovery of local planar surface patches from two shift/spacevariant defocused images. It is based on a recently proposed technique for in...

We present a focus-based method to recover the orientation
of a textured planar surface patch from a single image.
The method exploits the relationship between the orientation
