Abstract	This paper presents a new mode decision for the depth maps intra-frame prediction in 3D-HEVC. The proposed technique decides if the traditional High Efficiency Video Coding-based (HEVC) intra-frame prediction should be performed or skipped. This technique is inspired by the fact that traditional intra-frame prediction may generate artifacts in the synthesized views when an edge is encoded. The Simplified Edge Detector (SED) algorithm has been proposed to classify if a block contains an edge or a nearly constant region demanding a minimum processing overhead. Through software evaluations, SED algorithm was capable to obtain an average complexity reduction of 23.8% for depth maps coding with no quality losses.
