| Abstract(in English) | One category in fast full-search block matching algorithms (BMAs) is based on the fast Fourier transformation (FFT). For block matching, conventional methods in this category fit the macroblock size to the search window size by zero-padding. This property arises a problem that the memory consumption and computational complexity heavily depend on the size difference between the macroblock and the search window. This paper, thus, proposes a novel FFT-based BMA which overcomes the above mentioned problem. The proposed method divides the search window to multiple sub search windows to versatilely control the difference between the macroblock and the search window sizes. Simulation results show the effectiveness of the proposed method. |
