In　this　paper,　a　fast　algorithm　is　proposed　to　speed　up　the　motion　and　disparity　estimation　in　stereoscopic　video　coding.　Based　on　the　stereo-motion　consistency　constraint,　an　iterative　search　strategy　is　suggested　to　get　the　motion　and　disparity　vectors　simultaneously.　A　credible　base　vector　selection　scheme　and　an　adaptive　search　range　adjustment　technique　are　designed　to　further　strengthen　the　iterative　search.　Results　show　that　the　complexity　can　be　significantly　reduced　compared　to　the　JMVM　full　search　with　a　negligible　quality　drop.　©　2011　IEEE.
