Modelling of Eyeball with Pan/Tilt Mechanism and Intelligent Face Recognition Using Local Binary Pattern Operator

This paper describes the vision system for a humanoid robot, which includes the mechanism that controls eyeball orientation and blinking process. Along with the mechanism designed, the orientation of the camera, integrated with controlling servomotors. This vision system is a bio-mimic, which is  designed to match the size of human eye. This prototype runs face recognition and identifies, match...

A Visual Landmark Recognition System for Topological Navigation of Mobile Robots

This paper describes a vision-based landmark recognition system for use with mobile robot navigation tasks. A search algorithm based on genetic techniques for pattern recognition in digital images is presented. The developed system allows the topologic localization of a mobile robot using natural and artificial landmarks. Text strings inside landmarks can be read and interpreted, if

Graph-based representations and techniques for image processing and image analysis

In this paper we will discuss the use of some graph-based representations and techniques for image processing and analysis. Instead of making an extensive review of the graph techniques in this field, we will explain how we are using these techniques in an active vision system for an autonomous mobile robot developed in the Institut de Robòtica i Informàtica Industrial within the project “Activ...

Dual-Circle Self-Localization Algorithm for Omnidirectional Vision Robots

This paper proposes a new self-localization algorithm, called dual-circle self-localization algorithm, for use in omnidirectional vision robots. When an autonomous robot navigates in the field, it senses the environment by an omnidirectional vision device fitted on the robot. The landmarks information is acquired by using image processing and pattern recognition techniques. Robot position on th...
