O'Brien and Jain 1984 : This paper presents a new stereo approach. Two or more images of a scene containing stationary objects may be obtained by moving a camera by a known distance along its optical axis. It is shown that the displacement of a point in the Ego-motion Complex Logarithmic Space depends only on its depth. This fact can be exploited to obtain the depth of stationary surfaces. It was shown earlier that Ego-motion Polar Mapping allows easy segmentation of a dynamic scene. Thus, the approach of this paper, will allow depth recovery as a by-product in a dynamic scene analysis system. In this paper we present the mapping and demonstrate the feasibility of the proposed approach for recovering the depth.
