A novel algorithm for no-reference blur assessment in digital pictures is proposed. This metric is based on the evaluation of local phase coherence across the scales of an overcomplete wavelet transform. We compare the performance of the proposed method with four state-of-the art metrics using a large database containing both simulated and real blur.
