WebJun 15, 2024 · Hence, SSIM looks like a "better quality measure", but it is more complicated to compute (and the exact formula involves one number per pixel, while PSNR gives you an average value for the whole image). WebNov 3, 2024 · 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 …

This is stated in the documentation (but I think it should be indicated more clearly, perhaps in the description section). Also, a quick look at psnr's code confirms that the outputs are given in decibels: peaksnr = 10*log10(peakval.^2/err);
