Visual servoing is an approach to control motion of a robot manipulator using visual feedback signals from a vision system. Though the first systems date back to the late 1970s and early 1980s, it is not until the middle 1990s that there is a sharp increase in publications and working systems, due to the availability of fast and affordable vision processing systems (Hutchinson et al, 1996). The...

The goldfish is one of the few animals exceptionally well analyzed in behavioral experiments and also in electrophysiological and neuroanatomical investigations of the retina. To get insight into the functional organization of the retina we studied color vision, motion detection and temporal resolution before and after intra-ocular injection of neuropharmaca with known effects on retinal neuron...

Motion detection is a very important problem both in video image coding and in computer vision. In video coding, motion detection is a necessary task for motion-compensated predictive coding and motion-adaptive frame interpolation to reduce the required channel bandwidth. In computer vision systems, motion detection can be used to infer the 3-D motion and surface structure of moving objects wit...

The subject of motion has been the center of interdisciplinary studies since the time when Zeno posed his paradox circa 500BC. However, computer vision, the use of a camera and a computer to recognize objects, people and/or events automatically, is a relatively young field of research. Its development began in the early 1960s; however, it has matured fairly quickly. Today, it is contributing to...

PURPOSE To assess the possible effects of retinal prosthesis implant location on the initiation and stability of pursuit eye movements. METHODS Six normally sighted subjects visually tracked a horizontally moving target in natural vision and in simulated prosthetic vision. Subjects were instructed to press a key when the target jumped. Prosthetic vision was simulated with a 10 x 10 array of 1...

This paper deals with the design and the development of an equipment, called DDI, as acronym for Disease Detector, developed for the quantitative analysis of neuromotor diseases. It measures the reaction of a person evaluating in the motion of one finger of the hand the time response, the velocity of phalanxes, the force exerted from the finger against a button. The condition of motion are ball...

In addition to depth cues afforded by binocular vision, the brain processes relative motion signals to perceive depth. When an observer translates relative to their visual environment, the relative motion of objects at different distances (motion parallax) provides a powerful cue to three-dimensional scene structure. Although perception of depth based on motion parallax has been studied extensi...

Design of automated video surveillance systems is one of the exigent missions in computer vision community because of their ability to automatically select frames of interest in incoming video streams based on motion detection. This research paper focuses on the real-time hardware implementation of a motion detection algorithm for such vision based automated surveillance systems. A dedicated VL...

The recovery of motion for a class of movements in the space by using the perspective observation of one point is considered in this paper. The motion equation can cover a wide class of practical movements in the space. The estimations of the position and motion parameters which are all time-varying are simultaneously developed in the proposed algorithm. The formulated problem can be converted ...
