Abstract: The invention refers to a system (100) for assessing the quality of a physical product (111). A device (110) provides visual image data of the product and comprises a) a lighting setup comprising a lighting device (112) adapted for lighting the product and b) a camera (113) adapted for detecting light from the lighting device to generate visual image data of the product based on the detected light. An apparatus (120) assesses the quality of the product and comprises a) a providing unit (121) adapted to provide a trained machine learning based assessment model, wherein the model has been trained based on historical visual image data, and wherein the trained assessment model is adapted to determine a quality of the product, and b) an assessment unit (123) adapted to assess a quality of the product by applying the trained assessment model to the visual image data.

Abstract: The present invention is in the field of methods for determining material properties from foam samples. It relates to a computer-implemented method for determining a material property of a foam sample comprising (a) providing a representation of the sample, (b) extracting at least one structural feature from the representation, wherein the at least one structural feature comprises walls, struts, or nodes (c) providing the at least one structural feature to a material model suitable for obtaining at least one material property from the structural feature, and (d) outputting the at least one material property received from the material model.
