View　synthesis　optimization　(VSO)　allows　3D　video　system　to　improve　the　quality　of　synthesized　views　(SVs).　Based　on　the　latest　segment-based　VSO　scheme,　we　find　that　not　all　of　the　intra　mode　and　skip　interval　are　necessary　to　be　considered.　Therefore,　in　this　paper,　an　early　determination　of　intra　mode　and　optimal　skip　interval　based　on　VSO　scheme　in　3D-HEVC　is　presented.　First,　we　discuss　a　measure　to　select　the　best　intra　mode.　Then,　we　decide　the　optimal　skip　interval　based　on　statistical　analysis.　Experimental　results　indicate　that　the　proposed　algorithm　achieves　a　reduction　of　21.711%　with　negligible　loss　in　rate-distortion　performance　compared　with　the　original　3D-HEVC　encoder,　and　the　encoding　time　has　also　reduced　to　7.869%　compared　with　the　others.　©　2019,　Springer　Nature　Singapore　Pte　Ltd.
