—This paper presents a novel patch-based approach for object tracking robust to partial and short-time total occlu-sions. Initially, the original template is divided into rectangular subregions (patches), and each patch is tracked independently. The displacement of the whole template is obtained using a weighted vector median filter that combines the(More)
This paper describes the Intelligent Virtual Teaching Environment (IVTE) implementation. IVTE software uses the newest technologies to develop educational software. Technologies like Multi-Agent Systems, Virtual Reality, Intelligent Tutoring Systems and Distance Learning are being used in it. The paper gives emphasis in reactive agents model and(More)
Estimating human pose in static images is challenging due to the high dimensional state space, presence of image clutter and ambiguities of image observations. In this paper we propose a method to automatically segment human subjects in images, based on dominant colors, and given the face captured by a face detector. The posture is estimated using a 2D(More)
