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.

Abstract: Disclosed herein is a method for extracting material information of an object from a pattern image of the object. The pattern image showing the object while the object is illuminated with a light pattern is received. The pattern image is manipulated to generate a partial image from the pattern image. Material information of the object is extracted from the partial image by providing the partial image to a data-driven model. The data-driven model is parametrized according to a training data set including partial images and material information. The extracted material information is provided.

Abstract: Disclosed herein is a system for determining a material of an object. The system includes an image providing unit, a material score determination unit, a material determination unit and an output unit. The image providing unit is configured for providing at least two images, each showing a part of the object. The material score determination unit is configured for determining a material score for each of the at least two images, the material score being indicative of a presence of a predefined material in the respective image. The evaluation unit is configured for evaluating the material scores determined for each of the at least two images. This material determination unit is configured for determining the material of the object based on the evaluation. The output unit is configured for outputting the determined material of the object.
