Abstract
In the past, evaluation of the effectiveness of optical flow algorithms on real scenes has been difficult due to a lack of complex test data for which the correct flow is known. In this paper, we give a detailed description of how a simple ray tracing technique can be used to generate ground truth motion fields for the evaluation of optical flow algorithms on scenes of arbitary complexity.
