+### 使用方法：
+1.在本地bin文件夹下放置含有dcm文件的文件夹foldName
+2.编译
+mkdir build
+cd build
+cmake ..
+make
+
+3.执行,检测结果保存在Result文件夹内
+cd ../bin
+mkdir Result
+./Ellipse foldName
+
+
+### 改进措施
+1.先后高斯滤波(去除噪声)、双边滤波(保边去噪)的图像预处理
+2.修改圆检测最大圆半径为40(某些图像无法检测到大圆)
+3.修改圆检测的源码，将HoughCircleEstimateRadiusInvoker函数中的accThreshold传入参数改为原先的一半：
+效果：累加器->潜在圆心：仍使用accThreshold确保数量可控
+      潜在圆心->计算半径后的圆心：使用accThreshold/2,防止某些小圆无法被识别
