  • circular-birght-target-detect
    首先利用形态学开运算将图像中小于结构元素的亮点去掉,利用源图像与处理后的图像作差,对差图像进行阈值分割,得到二值图像,将二值图像中的一些干扰区域去掉,提取二值图像中的圆形区域,并在源图像上对小目标进行标记,实现对圆形亮目标的检测(Remove the area in the image smaller than structural element by morphologic open operation,receive image A,original image subtract image A,threshold segmentation for difference image,receive binary image,remove the interference region in the binary image,then extract circular area,and sign the target in the original image. Realize the circular bright target detection)
