Fig. 2From: Reliable 3D video streaming considering region of interestPDF of the depth’s pixel variations. The probability density function of the depth’s pixel variations for the first frame of video “Interview” (left) and “Orbi” (right). As can be seen, three regions are distinguished for both video tests. They are blocks with depth variation very close to zero, between zero and one, and greater than one (approximately)Back to article page
