Method and device for encoding a depth map of multi viewpoint video data, and method and device for decoding the encoded depth map

摘要

A method and apparatus for decoding the depth map of multi-view video data are provided. The method includes splitting a block of restored multi-view color video frame into a partition based on a pixel value of the block of the prediction-encoded and restored multi-view color video frame; obtaining a parameter indicating correlation between block partitions of the multi-view color video frame and block partitions of the depth map frame using peripheral pixel values of the block partitions of the multi-view color video frame and peripheral pixel values of the block partitions of the depth map frame corresponding to the block partitions of the multi-view color video frame with respect to each of the block partitions of the restored multi-view color video frame; and obtaining prediction values of corresponding block partitions of the depth map frame from the block partitions of the restored multi-view color video frame using the obtained parameter.

1. A method of encoding a depth map of multi-view video data, the method comprising:
obtaining a multi-view color video frame and a depth map frame corresponding to the multi-view color video frame; prediction-encoding and restoring the obtained multi-view color video frame; splitting a block of the restored multi-view color video frame into at least one partition based on a pixel value of the block of the restored multi-view color video frame; obtaining a parameter indicating a correlation between each of block partitions of the multi-view color video frame and each of block partitions of the depth map frame by using peripheral pixel values of the block partitions of the multi-view color video frame and peripheral pixel values of the block partitions of the depth map frame corresponding to the block partitions of the multi-view color video frame with respect to each of the block partitions of the restored multi-view color video frame; and obtaining prediction values of the corresponding block partitions of the depth map frame from the block partitions of the restored multi-view color video frame by using the obtained parameter.
