The human detection and tracking in a video plays major roll in security systems. This paper proposes an approach to detect and track the persons in a video. This approach uses Gaussian Mixture Model to detect the person and Kalman filter to track the detected person. The processing time to detect the person is reduced by performing the detection operation on down-sampled video. After detecting the...
High accuracy surface figuring of light-weighted aspherical optical mirrors using conventional polishingtechniques becomes increasingly difficult with size as problems such as tool footprint, edge turndown become severe. Hence, a non-contact polishing process called “ion figuring” was evolved where in material removal is done by energetic ion bombardment. In this paper the development of an ion figuring...
