Compared　with　traditional　High　Efficiency　Video　Coding　(HEVC),　3D-HEVC　introduces　multi-view　coding　and　depth　map　coding,　which　leads　to　significant　increase　in　coding　complexity.　In　this　paper,　we　propose　a　low　complexity　intra　coding　algorithm　for　depth　map　based　on　end-to-end　edge　detection　network.　Firstly,　we　use　Holistically　Nested　Edge　Detection　(HED)　network　to　determine　the　edge　location　of　the　depth　map.　Secondly,　we　use　Ostu　method　to　divide　the　output　of　the　HED　into　foreground　region　and　background　region.　Finally,　the　CU　size　and　the　candidate　list　of　intra　mode　are　determined　according　to　the　region　of　coding　tree　unit　(CTU).　Experimental　results　demonstrate　that　the　proposed　algorithm　can　reduce　the　encoding　time　by　39.56%　on　average　under　negligible　degradation　of　coding　performance.　©　2020　IEEE.
