This paper attempts to present a comprehensive summary of research results in the use of
visual information to control robot manipulators and related mechanisms. An extensive …

The Doppler technique has traditionally been the method used to extract motion information
from ultrasonic echoes reflected by moving tissues. The Doppler technique has been around …

Background My interest in the area of visual servoing dates back to 1984 when I was
involved in two research projects; video-rate feature extraction1, and sensor-based robot …

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 …

A popular configuration widely used in a variety of robotic applications is to mount a camera
on the robot manipulator hand. Before performing a measurement task using such a system …

Most vision-based robot positioning techniques rely on analytical formulations of the
relationship between the robot pose and the projected image coordinates of several …

This paper deals with the recovery of 3D information using a single mobile camera in the
context of active vision. First, we propose a general revisited formulation of the structure-from …

The term active stresses the role of the motion or, generally speaking, the dynamic
interaction of the observer with the environment. This concept emphasizes the relevance of …

We propose in this paper a new class of vision-based behaviors that provide navigation with
self-positioning to an autonomous mobile robot. Self-positioning is performed by serooed …

We present a new active vision technique called zoom tracking. Zoom tracking is the
continuous adjustment of a camera's focal length in order to keep a constant-sized image of …
