Draw a circles
Hello everyone, there is a metal particle currently being analyzed.
I want to measure how many particles pass through the circle. The test has no results for a long time.
I have tried the method of the website, but how to present the border and turn it into an irregular curve?
08/17 : I have an idea. The number of red circles and black focal points divided by two is the number of grains that the circle passes through. But if there is a U-shaped particles, there will be one more particles. Could the system distinguish whether it is the same particles?
