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.
Claims20
A method comprising:
- determining a depth quality sensitivity measure for a multi-view coding block in a frame;
- computing a depth-based perceptual quantization scale for a two-dimensional (2D) coding block of the multi-view coding block based on the depth quality sensitivity measure;
