Abstract: A heterogeneous face recognition system includes a pre-trained face recognition network having an input channel configured to input a captured image including at least one face in a target modality into the pre-trained face recognition network. A prepended domain transformer block is prepended to the pre-trained face recognition network configured to provide a prepended input channel for the captured image in the target modality. The prepended domain transformer block is configured to transform the captured image from the target modality into a transformed-target modality image to be used as an input image for the pre-trained face recognition network.

Abstract: A general framework for building a biometrics system capable of capturing multispectral data from a series of sensors synchronized with active illumination sources is provided. The framework unifies the system design for different biometric modalities and its realization on face, finger and iris data is described in detail. To the best of our knowledge, the presented design is the first to employ such a diverse set of electromagnetic spectrum bands, ranging from visible to long-wave-infrared wavelengths, and is capable of acquiring large volumes of data in seconds. Having performed a series of data collections, we run a comprehensive analysis on the captured data using a deep-learning classifier for presentation attack detection. The invention follows a data-centric approach attempting to highlight the strengths and weaknesses of each spectral band at distinguishing live from fake samples.

Abstract: The method of generating a structured program defines physical, biological and/or physiological needs and objectives of a subject. A structured program of adapted physical and feeding activities is established based on the temporal articulation variables and provided to the subject by way of a terminal. During the course of a session of adapted and structured physical activities of the program, a physical state and/or a physical activity of the subject is captured through the physiological and/or motion sensors. During the course of the session, the physical activity, the feeding activity associated with the adapted and structured physical activity of the session in progress and articulation temporal variables are adjusted.

Abstract: An abrasive article includes a carrier element, an abrasive component, and a bonding region between the abrasive component and the carrier element. The abrasive component includes abrasive particles bound in a metal matrix. The abrasive component further includes a network of interconnected pores substantially filled with an infiltrant. The infiltrant has an infiltrant composition containing at least one metal element. The bonding region includes a bonding metal having a bonding metal composition containing at least one metal element. The bonding region is a region distinct from the carrier element and is a separate phase from the carrier element. An elemental weight percent difference is the absolute value of the difference in weight content of each element contained in the bonding metal composition relative to the infiltrant composition. The elemental weight percent difference between the bonding metal composition and the infiltrant composition does not exceed 20 weight percent.
