Abstract
A method of determining a quality measure for a processed video signal generated from an original video signal. A statistical metric for a value for a set of pixels of the original video signal is determined, and the statistical metric for the value for a corresponding set of pixels of the processed video signal is also determined. The quality measure for the processed video signal is then determined by comparing the statistical metrics for the original video signal and the processed video signal.
