Contrast effect on 3D and 2D video perception
There are many factors and parameters that have an effect on the perceptual quality of 2D and 3D media. This paper investigates how the contrast affects 3D and 2D perceptions. We implemented the double stimulus continuous quality scale method to conduct subjective tests that evaluate the perceptual quality of experience of 3D video and its 2D counterpart at different contrast levels between the object of interest and the background. Our test set-up guarantees that the results are independent of the brightness reduction caused by a specific 3D viewing/displaying technology. Statistical analysis shows that the effect of contrast on the perceptual quality of 2D and 3D videos is similar.
