The second edition of a comprehensive introduction to all aspects of mobile robotics, from
algorithms to mechanisms. Mobile robots range from the Mars Pathfinder mission's …

In this paper, we address the challenging problem of recovering the defocus map from a
single image. We present a simple yet effective approach to estimate the amount of spatially …

Three-dimensional television (3D-TV) is the next major revolution in television. A successful
rollout of 3D-TV will require a backward-compatible transmission/distribution system …

Defocus blur is nearly always present in natural images: Objects at only one distance can be
perfectly focused. Images of objects at other distances are blurred by an amount depending …

The classical approach to depth from defocus (DFD) uses lenses with circular apertures for
image capturing. We show in this paper that the use of a circular aperture severely restricts …

A computational camera uses a combination of optics and processing to produce images
that cannot be captured with traditional cameras. In the last decade, computational imaging …

In this paper, we consider the problem of imaging a scene with a given depth of field at a
given exposure level in the shortest amount of time possible. We show that by 1) collecting a …

Three-dimensional (3-D) displays provide a more realistic experience of entertainment by
providing its viewers an added sensation of depth by artificially exploiting light rays to …

In this article we describe a novel approach to obtain the position of a chequerboard corner
at sub-pixel accuracy from digital images. Applications of this method include …

Three-dimensional (3D) shape reconstruction is a fundamental problem in machine vision
applications. Shape From Focus (SFF) is one of the passive optical methods for 3D shape …
