Comparedwith the existing results, this method is simpler in computation and valid for the case of elliptical orbits with globaloptimality guaranteed.
与现有一些结果相比，这里提出的方法计算简单，而且适用于一般共面椭圆轨道情况，并保证全局最优性。

The drawbacks of simulated evolutionary algorithms are that the globaloptimality can not be always guaranteed because of randomicity and premature con vergence.
The experimental results show that this method has the advantages of robustness, globaloptimality and high convergent speed and it is feasible for optical flow estimation of nonrigid body.
