Abstract
There is provided a computerized method and system of controlling a quality measure in a compression quality evaluation system, the method comprising: calculating a value indicative of a characteristic of an input image; and configuring the quality measure upon a criterion being met by the value, the quality measure being indicative of perceptual quality of a compressed image compressed from the input image. The value can be a smoothness value indicative of an extent of smoothness of an input image, and the configuration of the quality measure can be performed upon a smoothness criterion being met by the smoothness value. Alternatively, the value can be a gradient value indicative of an extent of gradual spatial changes of an input image, and the configuration of the quality measure can be performed upon a gradient criterion being met by the gradient value.
