Abstract

If a dynamic scene is acquired using a translating camera and the camera motion parameters are known, then the analysis of the scene may be facilitated in a transformed space. It is shown in this paper that by using the complex logarithmic mapping with respect to the focus of expansion, the segmentation of the scene into its stationary and nonstationary components and the determination of the depth of stationary components can be achieved easily in the transformed image sequence. An added advantage will be the invariances offered by the complex logarithmic mapping.
