Scene Change Detection usingEdge Direction based on Intra Prediction Mode inH.264/AVC

Thispaperpresents anovelscenechangedetection methodusingedgedirection basedonintra prediction modein H.264/AVC. When scenechangeoccurs, thereislesstemporal correlation between frames. Therefore, mostofmacro-blocks are encoded inintra mode.Using this property, theproposed method calculates thepercentage ofintra modeblocks ineachpredictive frameinordertogetcandidates ofscene changeframes. Tofind accurate scenechanges, wegenerate anedgehistogram ofeach candidate witheight prediction directions ofintraprediction modeinH.264/AVC. We detect scenechangeframeswithl1- normofedgehistograms. Theexperimental results showthatthe proposal methodisefficient androbust. I. INTRODUCTION
