Satish Kumar Sahu* , Dolley Shukla

Motion estimation is early procedure for video compression and is related to the compression efficiency by reducing temporal redundancies. Motion estimation is the most important part of a video encoder and half of coding complexity or computational time depends on it. There were various ME algorithms proposed and implemented to minimize the computational time. H.264/AVC codec offers many coding technique for achieving high compression gains as compare to other standards. These techniques dramatically increase the computational complexity of the block based motion estimation, which consumes up to 80% of the entire encoder’s computations. In this paper, we proposed Star Diamond-Diamond Search Algorithm for Block matching motion Estimation technique. This proposed technique provides reduction in computational complexity and encoding time without compromising the quality of the video sequence.
