This　paper　presents　an　adaptive　segment-based　view　synthesis　optimization　(VSO)　for　depth　map　coding　in　3D-HEVC.　The　original　method　skips　lines　of　pixels　where　there　is　no　change　in　depth　data,　and　exhaustively　renders　pixels　from　all　the　rest　of　lines　to　get　distortions　from　synthesized　views.　It　brings　unnecessary　coding　operations　and　ignores　smaller　regions　which　can　also　be　skipped　in　VSO.　The　proposed　method　is　designed　to　skip　proper　segments　of　pixels　for　the　non-skipped　lines　based　on　both　of　the　texture　smoothness　and　depth　data　unchangeableness.　Experimental　results　show　that　the　proposed　method　can　achieve　low　coding　complexity　without　significant　performance　loss　for　the　synthesized　views.
