What is a good 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.

Why is SSIM better than MSE?

MSE will calculate the mean square error between each pixels for the two images we are comparing. Whereas SSIM will do the opposite and look for similarities within pixels; i.e. if the pixels in the two images line up and or have similar pixel density values.

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?

Peak signal to noise ratio (PSNR) and structural index similarity (SSIM) are two measuring tools that are widely used in image quality assessment. Especially in the steganography image, these two measuring instruments are used to measure the quality of imperceptibility.
