| 摘 要： | 在红外图像中微弱小目标的检测一直是研究的重点和难点。文中介绍了一种利用形态学的Top-hat算子检测方法，主工步骤是先对图像进行滤波，然后依据目标运动的连续性进行目标检测，并对检测所得的目标特性进行分析。实验表明，该检测方法十分有效，并且还发现图像序列中小目标的灰度和质心位置变化是有规律的，它可提高检测的准确性。

| Abstract: | Detection of dim target in infrared image is the emphasis and difficulty of target detection. A method of detection using the Top\|hat operator of morphology is proposed. Its main procedures are filtering the infrared image sequences, and then detecting the targets depending on the continuity of the movement of the targets. Some features of detected target are analyzed. The effect of the detection method is verified by the results of experiments. The characteristics of the gray and centroid of small target in infrared image sequences are also found, which is significant to improve the precision of detection. |
