To　save　bit-rate,　texture　synthesis　is　employed　in　video　coding　to　generate　similar　texture　instead　of　encoding　the　texture　region.　Without　mean　squared　error　(MSE)　as　the　distortion　criterion,　high　quality　but　different　texture　can　be　synthesized　with　few　bits.　One　key　problem　that　embarrasses　the　application　of　texture　synthesis　in　video　coding　is　how　to　merge　the　synthesis　technique　into　the　nowadays＇　I,　P,　B　frame　based　codec,　or　more　specifically,　how　to　perform　synthesis　cross　I-frame.　In　this　paper,　we　describe　a　new　synthetic　region　selection　strategy　which　can　achieve　smooth　transition　between　the　synthetic　frames　and　the　adjacent　non-synthetic　frames.　In　our　method,　I-frame　is　still　coded　using　MSE　as　its　distortion　criterion.　The　area　of　synthetic　region　should　increase　or　decrease　depending　on　the　distance　between　the　current　frame　and　the　nearest　I-frame.　The　nearer　is　the　distance　from　the　I-frame,　the　smaller　is　the　synthetic　region　in　the　current　frame.　Experimental　results　show　a　smooth　transition　is　achieved　using　our　selection　strategy　with　great　bit-rate　saving.　©　2009　Springer-Verlag　Berlin　Heidelberg.
