Three-dimensional　human　body　curve-skeleton　is　widely　used　in　pose　estimation,　skeleton　animation　and　other　fields.　This　paper　proposes　an　improved　l(1)　median　model　that　can　extract　three-dimensional　human　body　curve-skeleton.　The　model　includes　three-dimensional　human　body　reconstruction　from　multi-view　images,　interpolation　curve-skeleton　extraction,　l(1)　median　skeleton　completion,　and　continuous　frame　curve-skeleton　optimization.　Through　the　completion　and　optimization　processes,　the　curve-skeleton　we　extract　is　smoother　and　more　complete　compared　with　previous　methods.　We　conduct　experiments　on　multi-view　human　body　image　dataset　collected　from　light　field　acquisition　system.　Both　quantitative　and　qualitative　results　demonstrate　the　effectiveness　of　our　model.
