The edge of picture space and the direction of time or spatial change information can be extracted by applying wavelet decomposition, deleting a low frequency component and carrying out wavelet reconstruction after that, to the three dimension discrete image data which consists of the picture space and the time-axis of acquired video. This paper proposes the method of presuming the rotation component of the move property of a move object, i.e., a parallel displacement, and the direction ofdoi:10.3154/jvs.29.1075 fatcat:5o3bz46fmnbk5ixuxfjw7eygza
