What is SSIM in image processing?

Introduction — The Structural Similarity Index (SSIM) is a perceptual metric that quantifies image quality degradation* caused by processing such as data compression or by losses in data transmission.

What should be SSIM value?

The SSIM values ranges between 0 to 1, 1 means perfect match the reconstruct image with original one. Generally SSIM values 0.97, 0.98, 0.99 for good quallty recontruction techniques.

How to calculate SSIM in Matlab?

Calculate Structural Similarity Index (SSIM)

ref = imread("pout. tif"); H = fspecial("Gaussian",[11 11],1.5); A = imfilter(ref,H,"replicate"); Display both images as a montage.
