Abstract: A video super-resolution device includes a down-sampler, video super-resolvers, and a selecting/averaging unit. The down-sampler divides an input low-resolution video into a plurality of frame rates. The video super-resolvers are video super-resolvers trained at different frame rates, and perform super-resolution of the low-resolution video. The selecting/averaging unit selects a video super-resolver according to the magnitude of an optical flow obtained as a result of video super-resolution. Specifically, in a case where the optical flow has a value smaller than 0.5 pixels, the selecting/averaging unit makes selection such as not adopting a result of video super-resolution at a high frame rate. Finally, the selecting/averaging unit obtains a mean value of the selected video super-resolution result, and outputs a final high-resolution video.

Abstract: A heart rate information concealed video transmission device includes a transmitter and a receiver. The transmitter compresses an input video and transmits the compressed video to a network, and the receiver decodes a received compressed stream, and attempts heart rate estimation by rPPG and generation of a biometric identifier. In order to invalidate heart rate estimation by a biological information processor, a corrected video generator outputs a corrected video in which small temporal variation of the input video is suppressed.

Abstract: In a linear actuator, a slide table is attached to a cylinder body via a guide mechanism so as to be movable along the longitudinal direction of the cylinder body. The slide table includes a table body arranged above the cylinder body and extending in the longitudinal direction, and an end plate joined to an end of the table body in the longitudinal direction so as to be substantially orthogonal to the table body. The end plate includes a storage chamber provided on one surface thereof in the longitudinal direction facing a guide mechanism and depressed from the one surface in a direction away from the guide mechanism. For example, when the linear actuator is used in an environment where powder dust and the like is scattered, the storage chamber stores therein a solidified matter made up of the powder dust and the like.

Abstract: Generally, an information processing device according to one embodiment includes storage, a receiver, a detector, an extractor, and a position specifier. The storage stores therein, imaging positional information indicating, identification information on a landmark set, and registration landmark information, in association with one another. The receiver receives a captured image for position specification from an onboard device. The extractor extracts imaging landmark information serving as information on a detected landmark from the captured image for position specification. The position specifier specifies the position indicated by the imaging positional information associated with the identification information on the landmark set including the registration landmark information similar to the imaging landmark information as the position of a vehicle at time when the captured image for position specification is taken.

The one or more processors receive from an onboard device of a probe vehicle an image showing a vehicle group of one or more vehicles stopping on the same lane, imaging time of the image, and a position of the probe vehicle at the imaging time. The one or more processors select vehicle groups according to the imaging time and an imaging position. The one or more processors identify the selected vehicle groups as a vehicle queue. The one or more processors calculate a stopping vehicle-queue evaluation value. The one or more processors calculate a parking vehicle-queue evaluation value. The one or more processors determine whether the identified vehicle queue is the stopping vehicle queue or the parking vehicle queue.
