Large Displacement Optical Flow Computation without Warping
We propose an algorithm for large displacement opti- cal flow estimation which does not require the commonly used coarse-to-fine warping strategy. It is based on a quadratic relaxation of the optical flow functional which decouples data term and regularizer in such a way that the non-linearized variational problem can be solved by an al- ternation of two globally optimal steps, one imposing op- timal data consistency, the other imposing discontinuity- preserving regularity of the flow field. Experimental results confirm that the proposed algorithmic implementation out- performs the traditional warping strategy, in particular for the case of large displacements of small scale structures.
