Fast algorithm of detecting small target in varying background

WEI Min1,2,ZHOU Jin1,2,WU Qin-zhang1(1.The Institute of Optics and Electronics,the Chinese Academy of Sciences,Chengdu 610209,China;2.Graduate School of the Chinese Academy of Sciences,Beijing 100039,China)  
The double-gate filtering algorithm is powerful to restrain noise yet time consuming.In this paper,a fast double-gate algorithm is proposed.This algorithm stores temporary results using two arrays which are the same size with the image to represent the sum and square sum of all left-top pixels respectively.Therefore,the operation process of mean and variance computing for target windows and background windows are greatly reduced from M×N additions and one division to two subtractions,one addition and one division.Theoretically,the computation is only 3/M×N compared with traditional algorithm and not increasing with the increase of target and background window’s size(M and N are the height and width of the background window respectively) .After using double-gate filtering algorithm to restrain background and noise and to detect targets roughly,the continuity of moving target is used to eliminate false targets and to realize target detection.Experimental results show that this algorithm is able to detect small target effectively.
