WebThe operator circularity calculates the similarity of the input region with a circle. Calculation: If F is the area of the region and max is the maximum distance from the center to all contour pixels, the shape factor C is defined as: C = min (1,C') The shape factor C of a circle is 1. If the region is long or has holes, C is smaller than 1. WebLast weekend, I was in a very creative mood. Did some origami. It was fun!
