Recursive Non-Linear Estimation of Discontinuous Flow Fields

Abstract. This paper de nes a temporal continuity constraint that expresses assumptions about the evolution of 2D image velocity, or optical ow, over a sequence of images. Temporal continuity is exploited to develop an incremental minimization framework that extends the minimizationof a non-convex objectivefunction over time. Within this framework this paper describes an incremental continuation method for recursive non-linear estimation that robustly and adaptively recovers optical ow with motion discontinuities over an image sequence.
