Abstract

We describe the algorithm of multidimensional signals superposition for improving quality images of a multicamera video surveillance system. The quality of images is defined by the resolution of a video surveillance system. The multicamera video system includes the camera with low resolution for surveying in all fields of view and includes the camera with high resolution for recognizing small objects in a video frame. The possibility of switching between the cameras can be provided by the homography superposition of multidimensional television signals. The developed algorithm of the homography superposition includes two stages of processing. The first stage is rough superposition by the feature points. The second stage is accurate superposition by the modified Lucas-Kanade algorithm. The feature of the first stage is longtime of processing. The reason for this is the huge amount of possible variants of superposition. The reduction of processing time is provided by a procedure of removing wrong variants of matching points. The developed algorithm has been tested on real multidimensional television signals and the result of superposition was satisfactory.
