An Improvement of Optical Flow Estimation Based on Gradient

WEI Shuigen,CHEN Zhen,LI Ming(Center of Artificial Intelligence and Image Processing,Nanchang Institute of Aeronautical Technology,Nanchang 330034)  
An improvement of optical flow estimation based on gradient is presented in this paper.Motion object region is extracted from multi-frame images in image sequences by using similar difference method.The harmful effect on the motion edge by global smoothness constraint in Horn algorithm is weakened by algebraic operation.Experimental results show that this method is suitable and effective.
