Mean squared error in image processing
In statistics, the mean squared error (MSE) or mean squared deviation (MSD) of an estimator (of a procedure for estimating an unobserved quantity) measures the average of the squares of the errors—that is, the average squared difference between the estimated values and the actual value. MSE is a risk function, corresponding to the expected value of the squared error loss. The fact that MSE is almost always strictly positive (and not zero) is because of randomness or because the e… WebSep 15, 2014 · The second method is to use algorithms such as Mean Squared Error (MSE) or the Structural Similarity Index (SSIM).
