We present a probabilistic model of how viewers may use defocus blur in conjunction with
other pictorial cues to estimate the absolute distances to objects in a scene. Our model …

We propose a novel scheme to recover depth maps containing thin structures based on
nonlocal-means filtering regularization. The scheme imposes a distributed smoothness …

An optical diffuser is an element that scatters light and is commonly used to soften or shape
illumination. In this paper, we propose a novel depth estimation method that places a …

The distance of objects to an optical system is estimated. An optical mask Such as a
diffractive optical element, continuous phase mask, hologram, amplitude mask, or …

Discrete models are consistently used as practical models for image restoration. They are
piecewise constant approximations of true physical (continuous) models, and hence …

Shape from focus (SFF) is a technique to estimate the depth and 3D shape of an object from
a sequence of images obtained at different focus settings. In this paper, the SFF is presented …

A method to convert a 2D video or 2D still image into a depth map is presented. The depth
map can consequently be converted into a pair of right and left images for viewing on a …

Recent years have seen ambitious robotic exploration missions to other planets and a
renewed interest in sending humans beyond low Earth orbit. These activities give rise to a …

We propose a new method that extends the capability of shape-from-focus (SFF) to estimate
the depth profile of 3-D objects in the presence of structure-dependent pixel motion. Existing …

We present a novel stereo imaging technique called dual-focus stereo imaging or DFSI.
DFSI uses a pair of images captured from different viewpoints and at different foci, but with …
