Usage

  which = c("PSNR", "MAE", "MSE", "RMSE", "SSIM", "MAGE", "RMSGE"),
  mask = FALSE)

Value

A vector with names as specified in which.

Arguments

img

2D/3D image, object of class "aws", "ICIsmooth", "kernsm", "nlmeans" or array.

ref

Reference image (array, matrix or vector) for comparison.

which

Criterion to use for Quality assessment. Please specify a subset of "PSNR" (Peak Signal to Noise Ratio), "MAE" (Mean Absolute Error), "MSE" (Mean Squared Error), "RMSE" (Root Mean Squared Error), "SSIM" (Structural SIMilarity), "MAGE" (Mean Absolute Gradient Error), "RMSGE" (Root Mean Squared Gradient Error).

mask
