I want to ask, I want to split the green shoot target surface, I am using HSV color space, and through a van for low and high stipulate the scope of the green, the range of real I experimental observation, but the teacher said this not line, through calculation, I want to ask how to accurately calculate the scope of HSV green ah, the teacher said to use dajin division I more don't understand

CodePudding user response:

Dajin is the OTSU segmentation, I usually use CV_THRESH_OTSU in after the gray level of the image binarization,
If you are the teacher's request is for you to realize OTSU, then you can go to search OTSU c + + implementation,
