| 摘 要： | 针对复杂海面红外目标检测问题,利用剪切波变换优良的各向异性能力和系数的几何特性,提出了一种基于剪切波变换的复杂海面红外目标检测算法.该算法利用剪切波变换得到边缘图像,同时提供边缘的方向信息,极大提高了海天线的检测和识别概率;然后根据海天线位置进行边缘加权,抑制海杂波,保留目标信息;经过减行均值滤波,对加权边缘图像进行分割;最后,进行数学形态学处理,检测出舰船目标.实验结果表明,该算法可以在单帧图像中检出目标,并且对存在阳光亮带、海杂波等干扰的复杂海面背景取得较好的检测效果.

| Abstract: | Aiming at the infrared target detection issue on complex sea,using shearlet anisotropy and geometry characteristic of its coefficients,a shearlet-based infrared target detection algorithm on complex sea is proposed.The algorithm adopts shearlet to acquire edge image and obtain the direction information of the edge,which greatly improves the probability of detection and identification of the sea-sky line.Then,according to the sea-sky line position,the edge image is weighted,which restrains sea clutter and ke... |
