What are good SSIM values?

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.

Is SSIM better than Psnr?

Based on the results of tests on this research SSIM has a better sensitivity to detect distortions that occur due to embedding messages on steganographic color images when compared with PSNR, this is due to the way SSIM works that are designed based on the human visual system.

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 is Psnr and SSIM?

In this paper, we analyse two well-known objective image quality metrics, the peak-signal-to-noise ratio (PSNR) as well as the structural similarity index measure (SSIM), and we derive a simple mathematical relationship between them which works for various kinds of image degradations such as Gaussian blur, additive ...
