Abstract :
Binocular luster is an extremely salient effect seen in 3D when an object in each stereo image exhibits a different contrast polarity relative to the background. The object appears to shimmer, a phenomenon seen in nature and on 3D displays, which the Human Visual System rapidly detects. This binocular luster is also induced by compression of stereo imagery where corresponding blocks are quantized to different values. In this paper, we discuss the psychovisual background of binocular luster, introduce the "shine" artifact induced by compression, and present an algorithm for detection and removal of shine from JPEG compressed stereo images without introducing additional bitrate.
