Depth map upsampling with a confidence-based joint guided filter

作者:

Highlights:

• It proposes the confidence-based upsampling scheme for depth map.

• The confidence values are computed from the shape of edge and color-depth correlation.

• Then, the confidence values adjust the filter parameters for the guided filter instead of the geometric proximity.

• The guided filtering is iteratively applied to refine the unreliable regions.

• The proposed method greatly improves the qualitative and quantitative performance.
