An Objective Evaluation for Disparity Map Based on the Disparity Gradient and Disparity Acceleration

In this paper, we present a novel objective approach to evaluate the disparity map quality. The two indices which are disparity gradient and disparity acceleration are first proposed for the evaluation of the disparity map. These two indices are under the assumption that the disparity map should be smooth in the natural scene. The joint application of the two indices guarantees the effective and reliable evaluation. The experimental results demonstrate the perfect performance of the proposed approach especially under certain noise levels.
