A method is presented for depth recovery through the analysis of scene sharpness across changing focus position. Modeling a defocused image as the application of a low pass filter …
This paper presents a depth recovery method that gives the depth of any scene from its defocused images. The method combines depth from defocusing and depth from automatic …

A depth estimation algorithm proposed by AP Pentland (1987) is generalized. In the proposed algorithm, the raw image data in the vicinity of the edge is used to estimate the …
A new method of recovering depth, which uses only one camera equipped with a zoom lens, is presented. The gradient-based as well as the feature-based schemes for recovering depth …
