Application of improved optic flow field in the supervisory control of nuclear explosion

A improved Horn-Schunck algorithm method was proposed to judge nuclear explosion.The optic flow field of a consecutive sequence of frames of nuclear explosion was calculated and the picture of optic flow field was drawn.For example,the average horizontal optical flow field was 0.018181pixel/s with a mean square deviation(MSD)of 0.375775pixel/s and the average vertical optical flow field was -0.503308pixel/s with a MSD of 0.896142pixel/s at the 1159th frame and the 1160th frame.A preliminary judgment can be made that it is a nuclear explosion according the picture and velocities distribution.
