【Abstract】 Proposed in this paper is an illumination radiation-based optical flow field model for the motion detection of various objects in different environments.In the investigation,first,the parameters of the general dynamic image model are explained and amended in the Clifford algebra region.Then,according to the results deduced in the Clifford algebra region and obtained from experiments,a new optical flow field model is proposed based on the principle of movement vision-generating principle and the illumination radiation theory,to which a gradient field is applied for the purpose of improving the accuracy.Finally,a total variation algorithm is presented for the proposed model.Experimental results show that the proposed model can achieve accurate,continuous and consistent optical flow fields for the purpose of being generally used in different illumination conditions.更多还原
