| 摘 要： | 为了降低复杂背景对弱小目标探测的影响,本文提出了一种基于背景分类的弱小目标检测算法.背景分类的依据是背景的复杂度,本文用熵运算估计背景的复杂程度,同时为了简化算法,采用多分辨率的小波变换.再用模糊数学中的隶属度函数映射到模糊特征平面,作为背景因子图像.接着对背景因子图像进行最大熵阈值分割,将复杂的地面背景与平坦的天空背...

| Abstract: | A dim-small target detection algorithm based on the classification of the background is presented to reduce the influence of the complexity of the background. The classification of the background is based on the complexity of the background. The complexity of background is estimated by the entropy of the image. And the lower-resolution wavelet transform idea is introduced in order to simplify the algorithm. Then the entropy of the image is mapped to the fuzzy plane as a background factor image by the fuzzy ... |
