Quick robustness estimation method for optical flow field in noise environment

The invention relates to a quick robustness estimation method for optical flow field in a noise environment. According to the invention, based on an optical flow field estimation method (ML method) inthe noise environment, a penalty factor is introduced for enhancing the optical flow calculation robustness and a factor of momentum is added in an optical flow calculation iteration formula for shortening optical flow calculation convergence time so as to accelerate optical flow field calculation. An Euler-Lagrange equation is solved through minimizing an optical flow energy function based on avariational approach and a velocity field is solved through an iteration method. Simulation results show that after different gaussian noises are added into two continuous frames of pictures in a video, the method provided by the invention can distinctively improve the optical flow field calculation robustness, shorten the optical flow calculation convergence time and accelerate optical flow fieldcalculation compared with
