摘要 在简要描述条带式CCD(ChargeCoupledDevice)弹道相机测试系统中的计算机软件处理子系统的基础上,针对在图像处理过程中,中值滤波排序工作量多、速度慢、非实时性的缺点,提出了一种快速中值滤波法。其主要特点是充分利用相邻两个中值滤波窗口内信号数据的相关性,通过移出和移入一列像素,而保留其左边界和上边界窗口内的排序信息;仅对新移入的像素进行排序的方法,完成中值滤波处理。使传统算法的复杂度由O(D4)下降到O(D2),大大提高了运算速度。将此方法应用到测试系统中,取得了很好的效果,实现了系统实时性要求。 The software processing subsystem of the CCD(Charge Coupled Device) ballistic camera detection system is studied. In order to solve the problem that the speed of median filtering is slow because of a lot of sorting, a new algorithm of median filtering based on coherence of data adjacent windows is proposed in image processing course. It completes the median filter processing by arranging only the added column of pixels while the rest of the arranged pixels remain unchanged when one column of pixels is deleted and another column added. The new algorithm can reduce the complexity of traditional median filtering algorithm from O(D^4) to O(D^2). Its result of application in detection system turns out to be satisfactory. It realizes the real-time need of the system.
