序列图像中动目标定位

给出了一种新的动目标定位方法，它可以快速准确地从复杂背景中确定动目标的位置和大小，此法充分利用序列图像特性，采用减影法提取动目标，由于实际情况中噪声无法避免，故提出了快速中值滤波方法以有效地滤除大量噪声，为了快速准确地定位目标，事先采用了映算法，然事提出了一种区域生长分割算法ＲＧＳＡ（ＲｅｇｉｏｎＧｒｏｗｉｎｇ Ｓｅｇｍｅｎｔａｔｉｏｎ Ａｌｇｏｒｉｔｈｍ）定位动目标，ＲＧＳＡ还适用于多目标情况，

A Location Method of Moving Object from image Sequence

A new Location method is proposed.The task of our location method is to design a frame to snap the moving object,the frame is minimized but still include the object.For locating the moving object accurately,mapping is used firstly to make the object conspicuous and RGSA(Region Growing Segmentation Algorithm)is suggested secondly to locate the object.Owing to the fact that there is a large quantity of noise existing in our task, two fast median filters are proposed to remove a large of noise effectively.This method can also work on multi-object case.In addition, making use of the adjustment of mapping coefficient,we can take the pyramid structure RGSA to locate the object more accurately and fast.Experimental results show the effectiveness of our method.
