Visual Interpretation of Cylindrical Deformation - A Sideways Look at Contour Motion

This paper presents a new technique for the interpretation of the changing intensity image generated by a cylindrical Lambertian surface undergoing a stretching motion, such that it may be regarded as a deforming curve in a plane. The method, based around the rate of intensity change, uses a regularisation-style approach to estimate the tangential and normal velocities along the surface, assuming knowledge of the initial surface structure and the motion of the endpoints.
