<p>A system (100) and method (200) are provided for unified visual measurement of blur and noise distortions in digital image data, the system including a processor (102), an input adapter (112, 114, 128, 130) in signal communication with the processor for receiving digital image data, a visual discrimination model (VDM) simulation unit (170) in signal communication with the processor, a just noticeable difference (JND) analysis unit (180) in signal communication with the processor, and a JND selection unit (190) in signal communication with the processor; and the method including receiving (212) digital image data, simulating (214) a single-ended VDM, analyzing (216) individual JND channels, including the responses of the highest spatial frequency channel(s), and selecting (218) a reference JND level corresponding to low noise and blur distortions.</p> |
