1. A method for encoding a multi-view frame in a video encoder, wherein the multi-view frame comprises a plurality of two-dimensional (2D) frames, the method comprising: 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.
