| Abstract: | This paper proposes an invariance based recognition scheme for scenes with multiple
repeated components. The scheme considers three component subsets which characterize the scene completely. Each such three component subset is reconstructed using single image based information.We have developed a mathematical framework
for the projective reconstruction based on relative affine structure of each such three
component building block. This is extended to the case when each of the components
is a quadric. A set of projective invariants of three quadrics has also been obtained by us. Although the reconstruction scheme is general and applicable to all multiple repeated components, it requires the computation of infinite homography. The infinite homography and hence the reconstruction scheme are only image computable with the given information in the case of translational repetition. We therefore develop a recognition strategy for the specific case of translationally repeated quadrics.As a... |
