Abstract: Disclosed herein is a method for authenticating an object. A pattern image is received showing the object while it is illuminated with a light pattern including one or more pattern features. From the pattern image pattern features located on the object are selected based on information indicating the position and extend of the object in the pattern image, several cropped pattern images are generated by cropping the pattern image based on the selected pattern features, where a cropped pattern image has a predetermined size and contains at least a part of one of the selected pattern features. The object is the authenticated by providing the cropped pattern images to a machine learning based identification model which has been trained such that it can authenticate an object based on the cropped pattern images as input. The authentication of the object is then outputted.
