| Abstract: | In this paper, a new method of representing a conic in three-dimensional space is proposed. The concept of the coordinates of the conics in two-dimensional and three-dimensional space is defined. The definition of the optical flow of a conic is given based on a time-varying image and consecutive images. The edge points with single pixel width have been obtained by using of the algorithms of edge detector, edge thinning and contour following from consecutive images, and the edges obtained are represented as conics. The computation of the optical flows of conics has been accomplished. |
