摘要
本文研究用高频图像滤波器去除背景干扰，提取可能的弱目标，进一步用假设检验分离出可能的弱目标。导出图像流约束方程，提出一种基于图像流和运动连续性分析的弱目标检测方法。该方法在强噪声背景和复杂背景下有良好的检测性能，计算机模拟实验检验了方法的性能。
It is considered in this Paper that a high pass filter for extracting possible dim target from spurious background signals, in which the relevant image flow constraint equation is derived and a dim target detection technique based upon image flow and motion continuity analysis is proposed. The technique is proved out by computer simulation of keeping good performance in detecting dim target in heavily confused or complex background.
