Abstract: Embodiments include a computer implemented method of processing images of material surfaces to identify defects on the imaged material surface, the method including training a neural network to generate reduced-defect versions of training images of material surfaces; acquiring an image of a subject material surface; inputting the acquired image to the neural network to generate a reduced-defect version of the acquired image; and comparing the reduced-defect version of the acquired image with the acquired image to identify differences. Defects on the subject material surface at locations of the identified differences are identifiable.

Abstract: A living body sensor obtains a plurality of living body images along an authentication-target living body, and a shape sensor obtains shape information corresponding to each of the plurality of living body images. A processor determines a position of a part of the authentication-target living body captured in each of the plurality of living body images, according to the shape information corresponding to each of the plurality of living body images. The processor compares a biometric feature of each of the plurality of living body images and a registered biometric feature by using a determined position of the part of the authentication-target living body and performs authentication for the authentication-target living body according to a comparison result of comparing the biometric feature of each of the plurality of living body images and the registered biometric feature.

Abstract: When receiving a hello packet, a node registers information on a control header of the hello packet in a work table. The information on the control header of the hello packet includes a plurality of sets of an address, a destination, and ?Pav of a node. The node stores information, in which a set of an address, a destination, and ?Pav of the own node from the own node to the destination is added to the information on the control header, in the control header of the hello packet and transmits the hello packet. These processes are performed by each node included in an ad-hoc network.
