Abstract:
Method for image processing to detect a moving object comprising the steps of:a) receiving a plurality of two dimensional images representative of a scene, each image being taken at a respectively different time;b) computing a planar homography aligning a surface in the scene among the plurality of images;c) computing parallax vectors with respect to respective corresponding points in each of two images of the plurality of images;d) using the parallax vectors and additional information in the plurality of images, computing a parallax rigidity constraint for the plurality of images, the parallax rigidity constraint being independent of any epipole;e) applying the parallax rigidity constraint to a further plurality of points within the plurality of images in order to generate information representative of whether a given point within the plurality of images is consistent with the parallax rigidity constraint; andf) using the generated information to perform moving object detection related processing on the received plurality of images.
