This paper proposes a novel multi-layer homography algorithm for background modeling from a free-moving camera. Background is composed of many planes. Different planes satisfy with different homographies which can be found by our algorithm. Each pixel except for the moving pixel definitely belongs to some plane. Rectified by the corresponding homography, each static pixel in the shared view can find...
Segmentation of moving regions in outdoor environment under a moving camera is a fundamental step in many vision systems including automated visual surveillance, human-machine interface, tracking etc. It is also a challenging task due to camera motion, object motion, and outdoor scene challenges i.e. periodic motions of swaying of trees, gradual illumination changes, etc. In this paper, a wide area...
For video summarization and retrieval, one of the important modules is to group temporal-spatial coherent shots into high-level semantic video clips namely scene segmentation. In this paper, we propose a novel scene segmentation and categorization approach using normalized graph cuts(NCuts). Starting from a set of shots, we first calculate shot similarity from shot key frames. Then by modeling scene...
Foreground segmentation with moving camera is a challenging task due to the presence of parallax effect, registration error, scene variations in out door, and etc. Currently, background modeling techniques either assumes correspondence among pixels in concurrent frames or do not model it explicitly. The contribution by this paper is in two folds. First, we achieve a new background model by introducing...
