Just to be sure, is the module you mentioned called MeasureObjectSizeShape? I couldn’t find one called MeasureObjectAreaShape and assumed the former is what you meant.
Unfortunately I couldn’t find much in the help to do with using that module, but maybe I’m looking in the wrong place. The ‘?’ button only brings up generic information. I guess I have to ask it to calculate Zernike features?
In the FilterObjects module there’s an option to then filter by AreaShape, but I couldn’t see any explanation of which I should use to filter for only regularly shaped objects. I know compactness measures roundness, but I figure that’s more for assessing circle vs oval than oval vs irregular shape.
Sorry for being a pain, and thanks for your help!
