New method of the human body pose estimation based on a single camera 2D observation is presented, aimed at smart surveillance related video analysis and action recognition. It employs 3D model of the human body, and genetic algorithm combined with annealed particle filter for searching the global optimum of model state, best matching the object’s 2D(More)
—An innovative application of gaze-tracking and acoustic vector sensors (AVS) technologies for guidance of moving pan-tilt-zoom (PTZ) monitoring camera is presented. Gaze-tracking is used to steer and to zoom the camera to the gaze focus area. Additionally, it is combined with audio processing in two scenarios. First is called " audio slave " : directional(More)
The article presents a method for video anonymization and replacing real human silhouettes with virtual 3D figures rendered on a screen. Video stream is processed to detect and to track objects, whereas anonymization stage employs animating avatars accordingly to behavior of detected persons. Location, movement speed, direction, and person height are taken(More)
