要約(日本語): The spatiotemporal spectra of a video that contains　a moving object form a plane in the three-dimensional (3D)　frequency domain. This plane, which is referred to as the　theoretical motion plane, reflects the velocity, which is calculated　from the slope, of the moving objects. In the present　paper, we propose a high-resolution frequency analysis method,　referred to as 3D non-harmonic analysis (NHA), which is only　weakly influenced by the analysis window. In experiments, we　verify the accuracy of 3D NHA and its usefulness for a sequence　containing complex motions, such as cross-over motion, by comparison　with 3D fast Fourier transform (FFT). The experimental　results show that increasing the frequency resolution contributes　to high-accuracy estimation of a motion plane.
