A New Anthropomorphic Visual Sensor

Anthropomorphic Visual Sensors

The tentative of reproducing a biological eye with artificial electronic devices has always had a major drawback. In fact there is an important difference between how a human eye sees the world and how a standard video camera does: while the common visual sensors generally have constant resolution on each part of the image, in their biological counterparts the picture elements are arranged in o...

A New Retina-Like Visual Sensor Performing the Polar Transform

This paper describes the development of an anthropomorphic visual sensor with retina-like structure to perform the polar mapping. The sensor consists of a dove prism for image rotation and a linear CCD sensor with 512 pixellline resolution, and holds approximately 45 Kbytes of image data. The retina-like sensor has variable resolution with increasing density towards the center of the visual fie...

Improving Energy-Efficient Target Coverage in Visual Sensor Networks

Target coverage is one of the important problems in visual sensor networks. The coverage should be accompanied with an efficient use of energy in order to increase the network lifetime. In this paper, we address the maximum lifetime for visual sensor networks (MLV) problem by maximizing the network lifetime while covering all the targets. For this purpose, we develop a simulated annealing (SA) ...
