Motion Tracking with an Active Camera
This work describes a method for real-time motion detection using an active camera mounted on a padtilt platform. Image mapping is used to align images of different viewpoints so that static camera motion detection can be applied. In the presence of camera position noise, the image mapping is inexact and compensation techniques fail. The use of morphological filtering of motion images is explor...
متن کاملBackground Compensation and an Active-Camera Motion Tracking Algorithm
Motion tracking using an active camera is a very computationally complex problem. Existing serial algorithms have provided frame rates that are much lower than those desired, mainly because of the lack of computational resources. Parallel computers are well suited to image processing tasks and can provide the computational power that is required for real-time motion tracking algorithms. This pa...
متن کاملReal-Time Tracking of Moving Objects with an Active Camera
This article is concerned with the design and implementation of a system for real-time monocular tracking of a moving object using the two degrees of freedom of a camera platform. Figure-ground segregation is based on motion without making any a priori assumptions about the object form. Using only the first spatiotemporal image derivatives, subtraction of the normal optical flow induced by came...
متن کاملRobust Real-Time Face Tracking Using an Active Camera
This paper addresses the problem of facial feature detection and tracking in real-time using a single active camera. The variable parameters of the camera (i.e. pan, tilt and zoom) are changed adaptively to track the face of the agent in successive frames and detect the facial features which may be used for facial expression analysis for surveillance or mesh generation for animation purposes, a...
