Abstract: Disclosed is an image processing method including: generating an initial denoised image with a reduced noise while preserving an edge in an input image; controlling an iterative operation performed based on energy defined in advance based on an initial residual component calculated from the input image and the initial denoised image; and separating the initial denoised image to a skeleton component and a residual component by the controlled iterative operation to generate the skeleton component as an output image.

Abstract: An illumination device emits light toward a moving subject. A controller controls light emitted from the illumination device so that the amount of light applied to the subject is adjusted to a specific amount or smaller. For example, when the illumination device emits light in a pulsed manner, the controller may control the amount of light applied to the subject by controlling at least one of the pulse width and the pulse intensity of the light. The controller may, for example, control the light emitted from the illumination device according to the distance between the illumination device and the subject.

Abstract: An authentication device includes an image acquisition unit, an identification unit, and an authentication unit. The image acquisition unit acquires an image of an eye of a subject. The identification unit identifies the colored pattern of a colored contact lens worn by the subject by comparing a reference image with the image of the eye. The authentication unit identifies the subject, using a feature in a region other than a colored region of the colored pattern in the iris region of the eye.

Abstract: Provided is a gate system arranged between a first region and a second region, including a guide that defines a movement path of a user from the first region to the second region and an imaging device that photographs the user to acquire an image used for biometric authentication. The movement path includes a first portion in which the user is photographed and a second portion through which the user passes after being photographed. The first portion extends from the first region toward the imaging device in a first direction that is parallel to an optical axis of the imaging device. The second portion extends from an end of the first portion in a second direction that is not parallel to the first direction.

Abstract: The video encoding device includes a predictor which performs a prediction process using intra-prediction or inter-prediction, and a coding controller which controls the predictor so that under a predetermined condition that pictures in the later display order are not coded before pictures in the earlier display order and that pictures in lower layers do not refer to pictures in upper layers, the predictor uses a picture closest in the display order to a picture to be coded as a reference picture when coding the picture referring to a picture in the lower layer.
