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 of roll, pitch and yaw from the change information in the dimension between space-time which carried out in this way and was detected.
