An adaptive quantization algorithm without side information for depth map coding

作者：

Highlights：

• A block-adaptive quantization scheme is carefully studied for depth map.

• Its theoretical derivations are provided by modeling of depth map and virtual view.

• The proposed model gives an efficient bit-allocation without side information.
