复杂背景下弱小点目标的检测算法

Detection Algorithm of Weak Point Targets under Complicated Background

本文讨论了复杂背景、强干扰条件下,对于移动平台下弱小目标的检测,提出了一种基于隐Markov模型的快速检测算法。该算法通过计算摄像机视场的运动,消除背景的干扰,通过计算模型中的目标转移概率和似然函数,确定点目标的运动轨迹。实验表明了该算法的有效性。

The weak point target detection from moving platform under complicated background and strong interaction is discussed. A novel algorithm based on HMM model is proposed. By the computation of the camera抯 movement, the disturbance of background can be eliminated. By the computation of the target抯 transition probability and likelihood function, the track of the target can be predicted. Experiment shows that this system is efficient.
