Webb9 maj 2024 · 顾名思义，SimpleBlobDetector是一种简单的算法，该算法由检测器的参数控制，并由以下几步组成： 1. 阈值处理：通过使用从minThreshold开始的阈值对源图像进行阈值处理，将源图像转换成多个二进制图像。这些阈值以thresholdStep大小依次递增直到maxThreshold，所以第一个阈值是minThreshold，第二个 … Webb6 mars 2015 · Hello, I am trying to use SimpleBlobDetector with only one of its params; filterByCircularity. But it alone doesn't seems to detect even a perfect circle. I have tried it with the min and maximum range but that also does not helps. If I use filter by area in combination with it, it seems to work; because of the area filters i think.
