WebJun 2, 2008 · Roundness compares measured data with a computer-generated reference circle. Roundness systems have four methods for comparing the measured data to a reference circle for evaluation. It is important to note the reference circle used should be related to the function of the finished component. WebCircularity 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 formula
