Detection of Optical Flow by Mode of Intersections of Constraint Equations

Abstract

The Gradient-Based method is widely used to estimate motion parameters from images and provide information about the 3-Dimensional structure of rigid bodies.
To determine the optical flow from the Gradient-Based method, global or local optimization is used as an additional constraint. However, these methods are sensitive to noise and the optical flow obtained gets corrupted gradually around the boundaries of the moving regions.
This paper presents a method to detect optical flow using the intersections of brightness constraint equations. This method can detect the fine optical flow around the boundaries of the moving regions and proves to be robust to image noise.
