Abstract: A device that is able to generate a segmentation mask for an object in a digital image is provided. To do so, the device comprises a processing logic that is configured to use a previously trained auto-encoder to encode the image, and decode the image generating an additional alpha channel, which defines the segmentation mask.

Abstract: An anomaly detection method of objects in a digital image is provided, wherein the image of the object is encoded and decoded by an autoencoder, then a pixel-wise difference is calculated between the input image of the object, and the reconstructed image of the object. Pixels whose pixel-wise difference is above a threshold are considered as dissimilar pixels, and the presence of clusters of dissimilar pixels is tested. A cluster of dissimilar pixel is considered as representing an anomaly.

Abstract: A weighing device, configured to measure at least the weight of a person or an object, comprising a control unit, a sensory plate, a top plate, spacer pads, interposed between the plates, wherein the sensory plate has an emission transducer configured to generate, a burst of Lamb waves at the surface of the sensory plate, a reception transducer, to receive echoed Lamb waves propagated through the sensory plate, the temporal profile of the echoed Lamb waves being dependent on the weight applied to the top plate and passed by the spacer pads to the sensory plate, wherein the control unit determines the weight applied to the top plate by analysis of the temporal profile of the echoed Lamb waves.
