Optical flow estimation using compensation method

In this paper we propose an optical flow estimation method based on compensating method by using spatiotemporal differentiation. Technique using spatiotemporal differentiation is one of optical flow calculation method. This method enables us to calculate velocity distribution rapidly, but the error in the approximation of derivative coefficients increases as the displacement of the moving pattern between the successive frames becomes large. We suggest a new system which expands the range of measurable velocity based on using spatiotemporal differentiation.
