一种改进的红外小目标检测与识别方法

A Modified Method for Detection and Recognition of the Infrared Small Target

研究天空背景下红外运动小目标的检测与识别 .对序列红外图像进行增强处理后 ,通过形态学滤波去除弱噪声 ,再用分割算法把目标和强噪声从背景中分离出来 ,最后用RMTI算法找出目标 ,并得出目标运动轨迹 .实验结果表明 ,该方法能有效地检测定位运动小目标 .

The infrared image is enhanced to improve its contrast, and the dim noises are removed by the use of the morphological filters. The segmentation algorithm are presented to separate the target and brighter noises from the background. According to the algorithm of recursive moving target indication(RMTI), the targets in an image sequence are recognized and the moving trajectory of the target is acquired. The experiment results indicate that this method can detect and locate small moving target validly.
