Curved artificial compound-eyes for autonomous navigation

by Andreas Brücknera, Wolfgang Bußa, Stéphane Violletb, Ramon Pericet-camarac, Hanspeter Mallotd, Andreas Bräuera
"... Natural compound-eyes consist of a large number of ommatidia that are arranged on curved surfaces and thus are able to detect signals from a wide field of view. We present an integrated artificial compound-eye sensor system with enhanced field of view of 180 ° × 60 ° due to the introduction of curv ..."

An Artificial Compound Eye Tracking Pan-Tilt Motion

by Gwo-long Lin, Chi-cheng Cheng
"... Abstract—The compound eyes of an insect can focus on prey accurately and quickly. From biological perspective, compound eyes are excellent at detecting motion. Based on the computer vision aspect, limited studies regarding this issue exist. Studies have verified that a trinocular visual system incor ..."

The Evolution of an Artificial Compound Eye by Using Adaptive Hardware

by Lukas Lichtensteiger, Ralf Salomon , 2000
"... Object avoidance is a fundamental task of autonomous, mobile robots. For this task, the pertinent literature proposes various architectures, which vary from simple Braitenberg vehicles to camera-lens systems inspired by the compound eyes of insects. Due to certain hardware limitations, existing rese ..."

research resorts to prespecified sensor systems that remain fixed during all experiments and does modifications only in the software components of the controllers. By contrast, this paper is about the direct evolution of an artificial compound eye in hardware. The hardware consists of a particular robot

Optic Flow Sensor for Artificial Compound Eyes

by Seokjun Park, Jihyun Cho, Kyuseok Lee, Euisik Yoon
"... Miniaturized low-power artificial compound eyes in a small form factor and a low payload can be a promising approach to provide wide-field information for micro-air-vehicle (MAV) applications. Recently, research efforts have been made to realize bio-inspired artificial compound eyes to mimic the wid ..."

Object and scene analysis by saccadic eye-movements: an investigation with higher-order statistics

by Gerhard Krieger, Ingo Rentschler, Gert Hauske, Kerstin Schill, Christoph Zetzsche , 2000
"... Based on an information theoretical approach, we investigate feature selection processes in saccadic object and scene analysis. Saccadic eye movements of human observers are recorded for a variety of natural and artificial test images. These experimental data are used for a statistical evaluation of ..."

Indicators for Social and Economic Coping Capacity - Moving Toward a Working Definition of Adaptive Capacity”, Wesleyan-CMU Working Paper.

by Gary Yohe , Richard S J Tol , Gary Yohe , 2001
"... Abstract This paper offers a practically motivated method for evaluating systems' abilities to handle external stress. The method is designed to assess the potential contributions of various adaptation options to improving systems' coping capacities by focusing attention directly on the u ..."

should produce unitless indicators that can be employed to judge the relative vulnerabilities of diverse systems to multiple stresses and to their potential interactions. An artificial application is employed to describe the development of the method and to illustrate how it might be applied. Some

Towards optimal sensor morphology for specific tasks: Evolution of an artificial compound eye for estimating time to contact

by Lukas Lichtensteiger - In , 2000
"... For a systematic investigation of the interdependence between an agent's morphology and its task environment we constructed a system that is able to automatically generate optimal sensor morphologies for given tasks. The system consists of a robot with an articial compound eye where the angular ..."

Diurnal changes in structure and function of the compound eye of Ligia exotica

by Takahiko Hariyama, V. Benno Meyer-rochdw - J. Exp. Biol , 1986
"... The ultrastructure of the retinula cells of Ligia exotica changes diurnally and in response to light/dark adaptation. At the low phase of electroretinogram (ERG) amplitude (at noon), the arrangement of microvilli is ordered and the rhabdom is of the open type. An irregular arrangement of microvilli ..."
