  • Publication number: 20190209052
    Abstract: A computer implemented method for detecting an attempt to spoof and facial recognitions apparatus determines for a plurality of spatially separated regions of a surface, a respective measure of at least one vital sign. A determination is made from the respective measures of at least one vital sign, homogeneity information associated with the respective measures, the homogeneity information is used to determine if said spatially separate regions of said surface are living tissue.

  • Publication number: 20190213736
    Abstract: The present invention relates to an apparatus (10) for tubulus detection from a tissue biopsy. It is described to provide (210) a plurality of 2D images of a tissue biopsy, wherein each 2D image corresponds to a different depth position in the tissue biopsy, and wherein each 2D image comprises image data of the tissue biopsy. A measure of a local variation of intensity is determined (220) in the image data of the tissue biopsy in a region of at least one 2D image. At least part of a tubulus is located (230) in the region of the at least one 2D image on the basis of the determined measure of the local variation of intensity. The locating (230) involves determining (240) locations in the region of the at least one 2D image where the measure of the local variation in intensity is below a threshold. Data representative of the location of the at least part of the tubulus in the region of the at least one 2D image are output (250).

  • Publication number: 20180360387
    Abstract: The present invention relates to a device, system and method for determining a vital sign of a person. To improve accuracy and reliability of vital sign determination, the device comprises an input unit (20) for obtaining a vital sign related signal of at least a body part of the person, from which a vital sign can be derived, a body part position determining unit (21) for determining if said body part of the person is in contact with a support or not and generating a contact signal indicating if said body part is in contact with the support or not, a quality metric setting unit (22) for setting, based on said contact signal, a quality metric for use in the determination of a vital sign of the person, and a vital sign deriving unit (23) for deriving a vital sign from the obtained vital sign related signal, wherein the set quality metric is used in the derivation of the vital sign and/or in a judgment of the reliability of a derived vital.
