| Research Abstract |
Optical flow is a vector which represents the motion of objects in images. The ordinary methods estimate optical flow instantaneously from two images. On the other hand, the proposed estimation method considers the intensity preservation law as an equation of time evolution of dynamical system and estimate from time sequence of images. The proposed method provides not only a new strategy for optical flow estimation but also some advantages. The first advantage of the method is that it simultaneously estimates the confidence of estimation, which enable us to evaluate the estimation results without the knowledge of true values. The second advantage of the method is that it detects discontinuity of optical flow, which is a higher level information of object motion.
