摘　　要：一种基于MIC的战场图像快速角点提取方法,先对低分辨率图像进行运算并提取出候选角点,在恢复图像的高分辨率后,对候选角点周围相关像素点进行进一步计算,将遗漏的角点也列入候选角点,减少原MIC算法由低分辨率到高分辨率的变化过程中角点的漏检概率,然后用梯度的概念对候选角点作进一步的筛选,以减少角点虚报的概率。在VC++6.0环境下,经编程实现验证该方法有效可行。Introduce a corner target extracting method of battlefield image based on MIC. First, extract candidate corners according to operation of low resolution image, after recovery image＇ high resolution progress calculates to candidate comers＇ correlative pixel, decrease leak check probability of MIC algorithm from low resolution to high resolution. Lastly, screen candidate corners by using grads, while accordingly decrease its probability. Program result proves the method is effective under VC＋＋6.0 environment.
