| 摘 要： | 研究了红外面阵传感器图像中小目标的特征,针对目标低信噪比的问题,提出了一种新的单帧红外图像小目标的检测方法。首先用改进的中值滤波对图像进行处理,抑制孤立噪声,然后对图像进行基于提升小波的分解,并用形态学对图像进行背景抑制,最后通过自适应阈值进行二值化分割检测出小目标。实验结果表明：该方法对面阵传感器红外弱小目标有良好的检测效果。

| Abstract: | Characteristics of small targets in infrared array sensor image are studied and a new method for detecting small infrared targets through one single frame is put forward to solve the problem of low signal noise ratio（SNR）target. Firstly,an improved median filtering is used to restrain isolated noise; Secondly, the image is decomposed by lifting wavelet and background is suppressed by morphology;Finally, small targets are detected by adaptive threshold to carry out binarization segmentation. Results of experiment show that this method can detect infrared small targets by array sensor effectively. |
