A new reduced reference objective quality metric for stereoscopic video

A new reduced reference (RR) objective quality metric for stereoscopic video is proposed that incorporates spatial neighbouring information. The contrast measures from grey level co-occurrence matrices (GLCM) for both colour and depth are the main parts of spatial information. Side information are extracted from edge information of original video and sent through an auxiliary channel. The other important factor in the proposed metric is the unequal weight of colour and depth views, which can maximise the performance of the proposed metric for some specific values. Performance of the proposed metric is validated through series of subjective tests to show how it correlates subjective quality scores. The average correlation of the proposed metric and subjective quality scores is 0.82 when colour to depth importance ratio is near 4.
