Methods for Image quality assessment

The standard metrics are mean-squared error, peak signal to noise ratio (psnr), and structural similarity (ssim).

Standard Images and Video

  • MSE
  • PSNR
  • SSIM

Foveated Quality Assessment

  • Lee et al.[1] propose Foveated signal to noise ratio (FSNR) which measures the signal to noise ratio in a curvilinear space. However they do not provide the exact equations to compute the curvilienar space.

Spherical Quality Assessment

  • Yu et al.[2] propose Spherical PSNR (SPSNR) and WSPSNR.
