Mean Squared Error ： Love It or Leave It ？

Why do we love the MSE ？ It is simple. It has a clear physical meaning. The MSE is an excellent metric in the context of optimization. The MSE is a desirable measure in the statistic and estimation framework.

What’s wrong with MSE ？

What are the alternatives ？ Structural similarity SSIM CW-SSIM

Visual information fidelity

From images to videos From visual to audio signals Optimization

Image restoration Signal with linear blur and additive noise Minimizes the MSE Maximizes the statistical version of the SSIM index
