We propose a fast motion search algorithm for H.264 motion estimation with variable block sizes. Motion estimation of H.264 encoder has larger computation complexity than existing video compression standards such as MPEG-4 and H.263 since search steps increase in proportion to the number of block sizes. Here, we employed two-stage motion estimation. In the… CONTINUE READING
