The Hough Transform (HT) is a digital image processing method for the detection of shapes which has multiple uses today. A disadvantage of this method is its sequential computational complexity, particularly when a single processor is used. An optimized algorithm of HT for straight lines detection in an image is presented in this article. Optimizat...

This paper describes the implementation of an algorithm that creates maps of an unknown environment for a robot. The algorithm is tested using a model of the Pioneer 2DX mobile robot found in the Player/Stage simulator, and a virtual environment that reflects a real place in the Autonomous University of Yucatan. The tests run simulations of the mob...
