An edge-based structural distortion indicator for the quality assessment of 3D synthesized views
3D-TV applications require the generation of novel viewpoints through Depth-Image-Based-Rendering methods. These synthesized views need to be assessed by a reliable quality metric. Most of the proposed metrics are inspired from 2D commonly used quality metrics. Yet, the latter were originally designed to address 2D compression distortions which are different from the distortions related to DIBR processes. We propose an edge-based method that indicates the level of structural degradation in the synthesized image. The first results are encouraging since the correlation to subjective scores is higher than other tested metrics.
