However, efficient exploitation of statistical dependencies measured by a mean squared error (MSE) does not always produce the best psychovisual result. One interesting approach is to only encode visually relevant information and use a different coding method for \"perceptually insignificant\" regions in the frame, which can lead to substantial data rate reductions while maintaining visual quality.
