Nonlinear least squares method is employed to solve the model to get the global motionarea of SR resolution.
最后基于非线性最小二乘法对模型进行优化求解，得出了SR重建图像及其全局运动域。

The steps are as follows: First, motionarea is extracted based on high-order statistics detection method and motion information of multiple frames.
其基本思想是：首先根据多帧帧差信息，基于高阶统计检测方法提取运动区域。

Firstly, a rough motion mask is obtained by introducing a motionarea segmentation method based on an improved accumulative frame- difference algorithm and optimal threshold segmentation.
