Clustering of Optical Flow Vectors

The basic approach which has been used in order to compute the cluster shown in Figure 6 has been outlined already.

Figure: The result of clustering OF vectors which constitutes an Object Image Candidate (OIC). The stylized arrow within the enclosing rectangle indicates the direction of image motion derived from the OF vectors which have been aggregated into this cluster. The (small) side of the enclosing rectangle in the direction of motion is assumed to represent the front side of the vehicle's projection into the image plane.
