An Affine Model for Optical Flow Estimation

Minas Spetsakis

Technical Report CS-ETR-94-02

York University

February 15, 1994


A model for optical flow is presented that assumes locally affine deformation of the moving image. It is shown that this formulation has clear advantages when the flow field is diverging, rotating or shearing. The problem is reduced to the solution of the partial differential equation of a simple form. Care has been taken to address the issue of the differentiation and preconditioning. The method was tested on real and synthetic images.
