Image-Quality-Assessment

FID

Pytorch and Python3 version of

  • FID(Fréchet inception distance)[1]: smaller is better.
  • SIFID(Single Image Fréchet Inception Distance)[2]: smaller is better.
  • C-FID(Clean FID)[3]: smaller is better.
  • LPIPS(Learned Perceptual Image Patch Similarity)[4]: smaller is better.

IQA

Matlab version of

  • SCOOT(Structure Co-Occurrence Texture)[5]: bigger is better.
  • PSNR(Peak Signal-to-Noise Ratio): bigger is better.
  • SSIM(Structural Similarity Index Measure)[6]: bigger is better.
  • FSIM(Feature Similarity Index Measure)[7]: bigger is better.
  • MAE(Mean Absolute Error): bigger is better.

NLDA

Matlab version of

  • NLDA(Null-space Linear Discriminant Analysis)[8]
