DLT (direct linear transformation) is one of the most popular methods of data simplification for camera calibration. An improved DLT method is proposed, the projective pseudo-inverse matrix is used to describe the relations between 2D coordinates and 3D coordinates, the improved DLT method can calculate the projective pseudo-inverse matrix based on only 4 known pixel points. The experiment results...
Video shot boundary detection is an important early stage of video analysis. In this paper, a new method for shot boundary detection using local color features (LCF) is presented. Firstly, interest points are detected for each frame. Then, local images are obtained based on the interest points. Finally, shot boundaries are detected based on the histogram difference of local images. LCF can overcome...
In order to overcome the disadvantages of traditional centralized video monitoring system or distributed systems based on wired network, we propose a framework for distributed video surveillance in heterogeneous environment. Video flows are compressed with the scalable video encoding standard MPEG-4 and transmitted over Internet or wireless network. Video surveillance can be performed wherever there...
