1. A method for encoding a multi-view frame in a video encoder, wherein the multi-view frame includes a plurality of two-dimensional (2D) frames, the method comprising: determining a depth-quality sensitivity measure for a multi-view coding block in the multi-view frame based on a depth of the multi-view coding block and a depth-quality sensitivity function, the depth-quality sensitivity function defining perceptual quality sensitivity of the multi-view coding block as a function of the depth of the multi-view coding block; determining a depth-based perceptual quantization scale for a 2D coding block of the multi-view coding block based on the depth-quality sensitivity 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.
