We present a quality assessment procedure for correspondence estimation based on geometric coherence rather than ground truth. The procedure can be used for performance evaluation of correspondence extraction schemes developed by researchers, as well as for online learning and adaptation aimed at better system performance. A very important aspect of the proposed procedure is that it considers uncertainty in the correspondence extraction, and encourages the evaluated methods to deal correctly with uncertainty. Other important strengths of the procedure are that it does not use any manual work, and that it does not put any strong constraints on the scene, but rather relies on geometric coherence in the motion. Thanks to these strengths, it can therefore be used with large amounts of real, potentially application specific data, or even data acquired during system operation. In the evaluation the correspondence extractor is handled as a black box producing a probability distribution for the local motion vector between a pair of image patches. The procedure is therefore quite general. We are making the evaluation procedure available for public use.
