How to get the SSIM comparison score between two images?

I am trying to calculate the SSIM between corresponding images. For example, an image called 106.tif in the ground truth directory corresponds to a 'fake' generated image 106.jpg in the fake directory. The ground truth directory absolute pathway is…

Image Processing - Does PSNR and SSIM metrics show smoothing (noise reduction) quality?

For my Image Processing class project, I am filtering an image with various filter algorithms (bilateral filter, NL-Means etc..) and trying to compare results with changing parameters. I came across PSNR and SSIM metrics to measure filter quality…

The interpretation of scikit-image SSIM (structural similarity image metric) negative values

I'm using scikit-image SSIM to compare the similarity between two images. The thing is that I get negative values, which are not favorable for my purpose. I understand that the range of SSIM values are supposed to be between -1 to 1, but I need to…
