一种基于自适应背景抑制的红外小目标检测方法

红外成像自动目标识别是精确制导武器的重要研究内容。为解决红外起伏背景下的小目标检测问题，提出了一种自适应的背景抑制方法，并对抑制背景后的图像进行了目标分割，最后用邻域法判决目标位置。实验结果表明，该算法能够从信噪比大于2．0的图像序列中检测出目标。

An Adaptive Background Suppression Algorithm for IR Small Targets Detection

ATR for IR imaging is a hot topic today. To detect small targets in IR image sequences with clutter background, an adaptive background suppression algorithm is put foreword, then targets segmentation are done based on the images with background clutter removed, at last neighborhood relationship is used to decide the position of targets. Experimental results show that this algorithm can detect small targets within the IR image sequence which SNR is bigger than 2.0.
