说明：  线性方程的解法,实现对运动目标的检测,针对可见光图像弱小目标检测中的背景抑制和去噪问题,提出了奇异值分解(Singular Value Decomposition,SVD)
(Linear equations, to achieve the detection of moving targets, in view of the weak target detection in visible light images in the background suppression and de-noising problem, a SVD (Singular Value Decomposition, SVD))
