Deep network based stereoscopic image quality assessment via binocular summing and differencing

Abstract

With the development of deep networks in dealing with various visual tasks, the deep network based on binocular vision is expected to tackle the issue of stereoscopic image quality assessment. Here, we present a stereoscopic image quality assessment method using the deep network with four channels together, which takes the left view, right view, binocular summing view, and binocular differencing view as the inputs of the network. The visual features are enhanced through the concatenation in a weighted way, so that the binocular vision can be adequately included in the binocular addition and subtraction information. Compared with the state-of-the-art metrics, the proposed method exhibits relatively high performances on four benchmark databases.
