Visual Interpretation of Lambertian Surface Deformation
Abstract
This paper considers the interpretation (as a three-dimensional velocity field) of the changing intensity pattern induced by a smoothly deforming Lambertian surface of uniform albedo illuminated by a distant point light source. The requisite "Intensity Rate Constraint " which is derived contains no terms relating to the tangential components of surface velocity, so the determination of the velocity field is ill-posed, exhibiting a form of "Aperture Problem". A stretch-based regulariser is applied to enable estimation of the velocity field and tests with synthetic data show a requirement for high accuracy. 1
