Abstract: A method for encoding a multi-view frame in a video encoder is provided that includes computing a depth quality sensitivity measure for a multi-view coding block in the multi-view frame, computing a depth-based perceptual quantization scale for a 2D coding block of the multi-view coding block, wherein the depth-based perceptual quantization scale is based on the depth quality sensitive measure and a base quantization scale for the 2D frame including the 2D coding block, and encoding the 2D coding block using the depth-based perceptual quantization scale.

Abstract: First and second views of a stereoscopic image are received. In response to determining that the stereoscopic image has a predominance of foreground features, a convergence plane of the stereoscopic image is adjusted to improve a depth resolution of at least one foreground feature within the stereoscopic image for display to a human by a display device. In response to determining that the stereoscopic image has a predominance of background features, the convergence plane is adjusted to position at least most of the stereoscopic image as background features for display to the human by the display device.
