Focuses on the structure of robot sensing systems and the techniques for measuring and
preprocessing 3-D data. To get the information required for controlling a given robot …

We present solutions to two problems arising in the context of automatically focusing a
general-purpose servo-controlled video camera on manually selected targets:(i) how to best …

Active, optical range imaging sensors collect three-dimensional coordinate data from object
surfaces and can be useful in a wide variety of automation applications, including shape …

In a large-scale space, structure is at a significantly larger scale than the observations
available at an instant. To learn the structure of a large-scale space from observations, the …

A new method is described for recovering the distance of objects in a scene from images
formed by lenses. The recovery is based on measuring the change in the scene's image due …

A method is proposed for recovering depth from a measure of the degree of blur of an edge.
Closed-form solution is derived for an edge which is a step discontinuity of intensity in the …

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 …

A vision system for use in a nobile robot systern, or in a fixed multi-tasking industrial robot
reqniras atten tive control. Attentive control refers to the process by which the direction of …

The Laboratory for Intelligent Systems of the Division of Electrical Engineering of the
National Research Council of Canada is intensively involved in the development of laser …

Advances in the semiconductor industry have had a tremendous impact on the field of image
processing. Within a few years industrial image processing has found its way from crude …
