WebCircularity is when all points of a body at any cross-sectioned area are equidistant from a reference axis. It is a 2-dimensional tolerance range that ultimately controls the overall geometry to form a circular body. Its value ensures the considering object is not too oblong, out of round, or ellipse in nature. WebDescription The 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 …
