ABSTRACT:
Ringing artifacts in digital images are predicted by determining a number of pixels of a block of pixels exhibiting luminance exceeding a luminance threshold adequate for detecting a ringing artifact and a number of these higher luminance pixels having sufficient contrast with neighbor pixels to be a likely source of a ringing artifact.
