Video surveillance typically relies on various methods of 3D scene reconstruction, such as people counting, and object detection and tracking. Video mosaicing is a related technology that enables an expanded view of a scene by pasting together frames from the video stream (superimages) of a moving single camera in real time. This technique provides better resolution than can be achieved with a conventional video camera. Well-known related applications in other fields include composition of panoramic pictures, alignment of satellite images, and generation of synthetic 360°-angle views. Given two frames of a scene, a general approach consists of finding a number of points in both images that correspond to the same objects in the scene. This makes it possible to compute a ‘transform’ that describes the geometrical relation between the views. Known as a planar homography, this transform can be obtained using robust estimation techniques on the point correspondences.
