Low complexity intra prediction mode decision for 3D-HEVC depth coding

作者：

Highlights：

•

• A new heuristic method to search for optimal wedgelet pattern for depth modeling mode (DMM1).

• A new early termination (ET) approach based on the smoothness of the processed block.

• Based on directional edge, a fast-angular mode decision algorithm is proposed.

• Achieved encoding time saving of about 35% with negligible BD-rate increase (0.023%) compared to HTM-160.
