Hello together,
I'm currently working with Knime to analyse images. I want to calculate the circularityof objects. I therefore started with self-drawn circles (see attached photos).
First I let KNIME find the circles in the photos and then it should calculate the circularity of these detected circles. Somehow, the circularity of perfect circles is always at 0.9. I came to the conclusion, that the calculated circularity is not the circularity of the circles but of the rectangles (in this case squares). Is there some other way to get the true circularity of the circles?
I would appreciate any advices very much. Thanks in advance!
Best regards,
Björn
