 note = {It is well established that optical flow contains information not only about the relative motion between the observer and his 3D environment  but also about the 3D structure of objects. But these informations are contained only in the translational component of optical flow. This paper will present a mathematical method of decomposition of spherically projected optical flow induced by curved paths of observation into rotational and translational omponents. This method uses only local operators  and is not dependent on global properties of optical flow. This method was applied to several synthetic optical flows., It is well established that optical flow contains information not only about the relative motion between the observer and his 3D environment, but also about the 3D structure of objects.
