In masking experiments, the task of an observer is to detect a target pattern in the presence of another pattern (masker). The detection threshold to the target depends on both the target and the masker. How a masker varies in a certain dimension can affect target detection reveal how the visual system responds to that dimension. In addition, the masking experiments concern with the discrimination behavior (target-plus-masker versus masker-alone), their data are commonly applied to the image quality assessment metrics in the development of commercial imaging products such as printers, scanners and digital cameras.
