| Abstract(in English) | In this paper, we first propose double-search-window block matching and then describe an FFT-based fast algorithm for it. The double-search-window defines two different-sized search windows, the inside-search-window and the outside-search-window, for block matching. The proposed method achieves the same accuracy performance as a direct SSD full search in the inside-search-window. And in the outside-search-window it offers a pseudo-full-search result. By evaluating the results comprehensively, the proposed method could achieve more precise motion vectors as well as generate the predicted pictures with fewer matching errors, but with almost the same computational load as in the conventional single-search-window block matching. |
