阈值图像和噪点

I'm doing a binary thresholding on an image using opencv, while moving or animating for example a circle on a binary image, there are few noise that appears around the moveable object. An image to illustrate what I mean is attached. How can I get rid of those artifacts? 解决方案 You could try to apply several cycles of the erosion algorithm (until there is only one object left) followed by same number of cycles of the dilation algorithm (the erosion/dilation pair is called opening)See here: http://en.wikipedia.org/wiki/Mathematical_morphology 这篇关于阈值图像和噪点的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
