When using “fit ellipse” on my objects, I understand that the returned parameters “Major” and “Minor axis” refer to an ellipse that best fit the object.
Is there also a value that describes how well the object fits to an ellipse in the first place, i.e. some R^2 or chi value?
The reason for me asking this is that I am trying to identify bacterial cells which usually have a very nice elliptical shape.
However the images also show many artefacts with objects that are “fuzzy” ore “edgy” and do not fit to an ellipse that well.
