This paper proposes a fast motion estimation algorithm for variable block-sizes by utilizing motion vector bottom-up procedure for H.264. The refined motion vectors of adjacent small blocks are merged to predict the motion vectors of larger blocks for reducing the computation. Experimental results show that our proposed method has lower computational complexity than full search, fast full search and fast motion estimation of the H.264 reference software JM93 with slight quality decrease and little bit-rate increase.
