This paper deals with the mechanical aspects of robot vision and focuses on the design and implementation of a high-performance system. The system is called CeDAR (Cable Drive Active vision Robot). As part of the research at the Robotic Systems Laboratory (RSL) to develop real-world vision systems, CeDAR is designed for speed and accuracy through its novel use of cables in zerobacklash transmis...

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...

Laboratoire d'Electronique, U.R.A 830 du CNRS, UniversitC Blaise Pascal, 63177 Aubitre Cedex, FRANCE email : 1egrandQlesmti.univ-bpclermont.fr Abstract Image processing applications need shorter processing times. This requires the parallelization of low and mid levels sequential process chains on specific machines. In this paper we present the implementation of a contour based image segmentatio...

In this paper we propose a method for transforming a 3D map of the environment, composed by a cloud of millions of points, into a compact representation in terms of basic geometric primitives, 3D planes in this case. These planes, with their texture, yield a very useful representation in robot navigation tasks like localization and motion control. Our method estimates the main planes in the env...

We describe a 3D vision system implemented upon a locally developed transputer-based hybrid parallel processing engine named MARVIN (Multiprocessor ARchitecture for VIsioN), hosted by a SUN workstation. In addition to the recovery of scene descriptions from edge based binocular stereo, the system incorporates a model matching algorithm which is able to accurately locate modelled objects within ...

MAVIS is a dataflow visual language for computer vision and image processing. It features a high degree of ‘liveness’ and compliance with user directives, providing a flexible environment for building and testing vision algorithms. MAVIS includes a number of features intended to support real-time or ‘active’ vision. Among these are flexible user and program control of communications and schedul...

When considering real-world applications of robot control with visual servoing, both 3D information and a high feedback rate are required. We have developed a 3D target tracking system with a 1ms feedback rate using two high-speed vision systems called Column Parallel Vision (CPV) systems. To obtain 3D information, such as position, orientation, and shape parameters of the target object, a feat...

-Light-adaptive algorithms~architectures are proposed for regularization vision chips. The adaptation mechanisms allow the regularization parameters to change in an adaptive manner in accordance with the light intensity of given images. This is achieved by adaptively changing the conductance values associated with massively parallel resistive networks. The algorithms/architectures are inspired ...

As a special type of object detection, pedestrian detection in generic scenes has made a significant progress trained with large amounts of labeled training data manually. While the models trained with generic dataset work bad when they are directly used in specific scenes. With special viewpoints, flow light and backgrounds, datasets from specific scenes are much different from the datasets fr...
