Abstract: A method and system for performing characterization of one or more materials. One or more materials are scanned by means of a sensory system including an X-ray sensor configured to perform multi-energy imaging for obtaining at least a lower-energy X-ray image and a higher-energy X-ray image. Images obtained by means of the sensory system are segmented, and for each segmented object, data indicative of an area density and data indicative of an atom number by analysis of the lower-energy X-ray image and the higher-energy X-ray image, and data indicative of the area density and atom number is determined by means of a calibrated model. Data indicative of a mass is calculated based on the data indicative of the area density and the data indicative of the area of each of the segmented objects. The data indicative of the atom number is provided as input to a trained neural network, wherein the trained neural network is configured to label each segmented object, and wherein the data indicative of the mass is coupled to each of the labeled segmented objects.

Abstract: A method and system for training a machine learning model configured to perform characterization of components in a material stream with a plurality of unknown components. A training reward associated with each unknown component within the plurality of unknown components in the material stream is determined, based on which at least one unknown component is physically isolated from the material stream by means of a separator unit, wherein the separator unit is configured to move the selected unknown component to a separate accessible compartment. The isolated at least one unknown component is analyzed for determining the ground truth label thereof, wherein the determined ground truth is used for training an incremental version of the machine learning model.

Abstract: A method and system for performing characterization of one or more materials. The one or more materials are scanned by means of a sensory unit including an x-ray sensor for obtaining at least one x-ray image. Segmentation of the at least one x-ray image is performed in order to separate one or more distinct objects in the at least one x-ray image. In the at least one x-ray image, segmented objects are selected. For each of the selected segmented objects in the at least one x-ray image, a transformation using a transformatio n model is computed, wherein each transformation is indicative of a three dimensional reconstruction of the respective selected segmented object in the at least one x-ray image. The selected segmented objects are characterized based upon its computed transformation.
