A distortion-agnostic video quality metric based on multi-scale spatio-temporal structural information
作者:
Highlights:
• Structural degradations due to video distortions considerably affect the perception of visual quality.
• LBP-TOP histogram is an effective way to measure the structural degradations in videos.
• Weighting the LBP using local magnitude based LBP significantly improves the performance without increasing histogram length.
• Multi-resolution analysis incorporates coarse-to-fine structures in quality assessment and enhances prediction accuracy.
• The proposed metric is computationally inexpensive and exhibits high correlation with the subjective ratings.
