Active vision systems, and especially foveated vision systems, depend on efficient
attentional mechanisms. We propose that machine visual attention should consist of both …

Depth from Focus (DFF) and Depth from Defocus (DFD) methods are theoretically unified
with the geometric triangulation principle. Fundamentally, the depth sensitivities of DFF and …

This book defines the emerging field of Active Perception which calls for studying perception
coupled with action. It is devoted to technical problems related to the design and analysis of …

In this paper, we provide a systematic study of the task of sensor planning for object search.
The search agent's knowledge of object location is encoded as a discrete probability density …

Here, this author attempts to tie the concept of active perception to attentive processing in
general and to the complexity level analysis of visual search described previously; the …

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 …

In binocular systems, vergence is the process of adjusting the angle between the eyes (or
cameras) so that both eyes are directed at the same world point. Its utility is most obvious for …

Techniques are proposed to support the video based development of systems for indoor
exploration with mobile robots. The technique of redundant programming is often used to …

Abstract Since Kepler (1604) and Descartes (1637),'vergence'(the angular rotation of the
eyes) has been thought of as one of our most important absolute distance cues. But …

This article addresses the problem of measuring reliabily the absolute three-dimensional
position of objects in an unknown and cluttered scene. It circumvents the limitations of a …
