Automatic Moving Object Segmentation from Video Sequences Using Alternate Flashing System
A novel algorithm to extract moving objects from video sequences is proposed in this paper. The proposed algorithm employs a flashing system to obtain an alternate series of lit and unlit frames from a single camera. For each unlit frame, the proposed algorithm synthesizes the corresponding lit frame using a motion-compensated interpolation scheme. Then, by comparing the unlit frame with the li...
متن کاملHigh Quality Video Acquisition and Segmentation Using Alternate Flashing System
A high quality video acquisition algorithm is proposed in this work. We construct a flashing system to capture lit and unlit frames alternately. We develop a reliable motion estimation scheme, which matches correspondences between an unlit frame and a lit frame. Then, we construct a high quality frame, which combines natural scene mood in the unlit frame and textural details in the lit frame. F...
متن کاملAutomatic Segmentation of Moving Object in Video Sequences
In content based video retrieval and concept detection systems video segmentation is the most important step. There are basically two methods for video segmentation, one is semiautomatic and other is automatic. A lot of work is already performed on this two approaches. Semiautomatic methodsrequires the user intervention to draw the boundary of object. Many applications require automatic segment...
متن کاملRobust 2D Moving Object Segmentation and Tracking in Video Sequences
− Unsupervised motion segmentation and tracking in video sequences is a complex task, requiring robust estimation and flexible modeling. The paper presents an unsupervised method of moving object segmentation and tracking in video sequences captured by static cameras. Central to our work is the nonparametric density estimation and the mean shift algorithm for finding local maxima of the probabi...
متن کاملAutomatic Segmentation of Moving Objects in Video Sequences
The emerging video coding standard MPEG-4 enables various content-based functionalities for multimedia applications. To support such functionalities, as well as to improve coding efficiency, MPEG-4 relies on a decomposition of each frame of an image sequence into video object planes (VOP’s). Each VOP corresponds to a single moving object in the scene. In this thesis, a new method for automatic ...
