摘要
文中采用红外图像的局部熵变化为检测准则 ,确定红外图像小目标位置 ,对较大的红外图像目标 ,局部熵突变发生在目标边缘 ,用本方法也可确定目标边缘。文章给出了算法的实现过程 ,最后 ,用海上红外小目标真实图像进行了实验 ,得到了满意的结果。
The method decides the infrared image of object location based on the decision criterion of local entropy change of infrared image. For the bigger infrared image of object, the method can decide the edge of infrared image of object. The detection process was presented in this paper. The detection experiments were performed for a set of real infrared image of small object on sea. The experimental results prove that the proposed approach is effective for detection of infrared image of small object.
