Moving object extraction from a video sequence plays an essential role for various machine vision applications such as video surveillance, traffic monitoring, and human motion analysis. There are two widely used methods for moving object extraction: the frame differencing method and the background subtraction method. Although the background subtraction method usually generates superior results to...
We present an optimum camera placement algorithm. We are motivated by the fact that the installation of security cameras is increasing rapidly. From the system cost point of view, it is desirable to observe all the area of interest by the smallest number of cameras. We propose a method for deciding optimum camera placement automatically considering camera specification such as visual distance, visual...
3D object data transfer was optimized to accelerate interactive 3D scene design and virtual-space layout applications. In these applications, downloading many 3D objects reduces the interactivity of the clients. We used level-of-detail based loading sequences and timing control methods to interleave data downloading and interactions. Experiments showed that the maximum interval between interactions...
