  • Patent number: 10713805
    Abstract: A method for encoding depth map image involves dividing the image into blocks. These blocks are then classified into smooth blocks without large depth discontinuities and discontinuous blocks with large depth discontinuities. In the discontinuous blocks, depth discontinuities are represented by line segments and partitions. Interpolation-based intra prediction is used to approximate and compress the depth values in the smooth blocks and partitions. Further compression can be achieved with of depth-aware quantization, adaptive de-blocking filtering, scale adaptive block size, and resolution decimation schemes.
