The motion estimation in applied television systems

Бесплатный доступ

The features of motion vectors field usage for motion estimation in applied television systems are reviewed. The analysis of main optical flow equation is given, also the high probability of abnormal motion vectors originating is shown. The efficiency estimations for different algorithms of motion vectors definition according to the test of significance (number of abnormal vectors in a total number retrieved) are adduced. A number of solutions permitting the accuracy and reliability of motion vectors estimation indispensable for their usage in applied television systems such as three components motion vector and method of their definition; the method of sub pixel motion vectors estimation; a posteriori estimation of motion vectors reliability; the vectorial median filtering procedure for obtained motion vectors field are written in detail
