Author: Wayne Rasband (email@example.com) Date: 2000/8/17 Source: Circularity_.java Installation: Circularity calculations are built into ImageJ 1.29 and later. Check "Circularity" in Analyze/Set Measurements and the Measure and Analyze Particles commands will calculate and display the circularity. Description: This plugin is an extended version of ImageJ's Measure command that calculates object circularity using the formulacircularity = 4pi(area/perimeter^2)A circularity value of 1.0 indicates a perfect circle. As the value approaches 0.0, it indicates an increasingly elongated polygon.
Note: this plugin does not work with the Analyze Particles command.
