Quality-Metrics-Evaluation

A set of full reference (FR) quality metric tested for 360° image quality assessment using equirectangular (ERP) format.

List of considered metrics

  • PSNR (Peak to Signal Noise Ratio)
  • WS-PSNR (Weighted Spherical Peak to Signal Noise Ratio)
  • S-PSNR (Spherical Peak to Signal Noise Ratio)
  • S-PSNR-NN (Spherical Peak to Signal Noise Ratio Near Neighbor)
  • SSIM (Structural Similarity Index)
  • MS-SSIM (Multi-Scale Structural Similarity Index)
  • GMSD (Gradient Magnitude Similarity Deviation)
  • VIFp (Visual Information FidelityP)
  • MAE (Mean Absolute Error)
  • RMSE (Root Mean Squared Error)
  • PAMSE (Perceptual Fidelity Aware Mean Squared Error)
  • RECO (Relative Edge Coherence)
