Transformation of Optical Flow by Camera Rotation

Abstract

The effect of camera rotation on the description of optical flow is analyzed. The transformation law of the parameters is explicitly given by considering infinitesimal generators and irreducible reduction of the induced representation of the 3D rotation group. The parameter space is decomposed into invariant subspaces, and the optical flow is accordingly decomposed into two parts, from which an invariant basis is deduced. A procedure is presented to test the equivalence of two optical flows and to reconstruct the necessary amount of camera rotation. The relationship with the analytical expressions for 3D recovery is also discussed.
