This paper describes motion detection method of moving objects. which do not change shape itself such as car. move smoothly. and do not suddenly turn. and which form is seen to be changed by 3-dimensional motion of objects, or operation of camera such as zoom. tilt, pan, and dolly. The proposed method is dividing objects into area where affine transformation is valid. and estimating affine transformation matrix in each area with similarity between frames. smoothness of motion. least square method. and dynamic programming. etc. after specifying detection, points on initial frame (and final frame in some cases)
