Its main steps are : 1 median filter to filter yawp ; 2 edge detecting ; 3 figure thinning ; 4 the calculation of center point and some other parameters , we put forward a new method with which we firstly give a self - adjust liner transform then we use robert edge detecting and we also give an four - adjacent - field method for edge thinning here ; secondly we repeat four steps above and use the center point as focus in the fourth image . after this we track the forecasting center point by kaveman filter and select two blocks for locating . lastly from the fifth photo on we mainly deal with the arithmetic for matching locating and recognition of focus except kaveman filter
然后在第四幅图像中：重复上述四步，以提取的形心为瞄准点，在选定瞄准点以后，为了在后续图像中匹配、定位、识别瞄准点，我们使用卡尔曼滤波求取跟踪预测的形心点并在瞄准点的周围选取两个匹配定位块：从第五幅图像开始，除了使用卡尔曼滤波求取跟踪预测形心点以外，主要执行匹配、定位、识别瞄准点的算法。
