I want to divide a group of images into parts for industrial application depending on the prismatic nature as rotational and non-rotational images. Rotational images (Part Family 2) are cylindrical disc shape whereas non rotational images (Part Family 1) are block or plate like prismatic images.

One possible option: Seperate each object, then create SURF features from each. Compare the SURF features from each object with your reference, if you have a match, then you found your object. Of course it needs to be a bit optimised, since different object will still share some feature points.

This is a similar case, they search for a different object in a crowded scene here https://de.mathworks.com/help/vision/examples/object-detection-in-a-cluttered-scene-using-point-feature-matching.html
