WebJan 16, 2024 · There are two ways to find if an image is similar to another image. First is to look at Mean Square Error ( MSE) and the second is Structural Similarity Index ( SSIM ). Left is MSE while right is SSIM They both look pretty scary but no need to worry. WebSep 15, 2014 · Equation 2: Structural Similarity Index. The SSIM method is clearly more involved than the MSE method, but the gist is that SSIM attempts to model the perceived change in the structural information of the image, whereas MSE is actually estimating the perceived errors. There is a subtle difference between the two, but the results are dramatic. cutz vinyl and craft supplies discount code
