Object and motion recognition using the plane plus parallax displacement of conics
Douglas R. Heisterkamp, Paritosh Bhattacharya · 2002
Parallax displacement is used to determine a relative 3D conic projective structure. This value is invariant between any number of views in time if the conic is not moving with respect to the plane of the homography. It can be used to determine conic correspondence between three simultaneous views. The corresponding conics may then be used to determine the epipolar geometry. This method of determining conic correspondence works with unknown and even changing epipolar geometry. The relative 3D conic projective structure may be used to segment groups of conics which have consistent motion.
