计算空化泡的半径并做出相应的图形，实现了空化泡的半径的可视化-Calculate the radius of cavitation bubbles and make the appropriate graphics to achieve a radius of cavitation bubble visualization

在视频图像处理中，二值图像中的前景目标有时候会产生空洞现象，此采用Opencv实现二值图像的空洞填充-Foreground objects in video image processing, binary image can sometimes produce cavitation, Opencv binary image hole filling
