Mod-rssim Best -

mod-rssim often implements a with shear suppression:

q_profile = [1.2, 1.0, 0.9, 1.2, 2.0] # at rho = [0,0.2,0.4,0.6,1.0] shear = derivative(q_profile) mod-rssim

# THE "ROOT" PART: Apply square root to the error # Standard dissimilarity = 1 - SSIM. We take the root to change perceptual weighting. dissimilarity = 1 - ssim_map root_dissimilarity = np.sqrt(np.abs(dissimilarity) + 1e-8) 2.0] # at rho = [0
