Abstract: Provided are an object detection device, POS terminal device, object detection method, and program capable of carrying out appropriate processing according to whether an object is covered by a translucent container. A distance measurement unit measures the distances to each position on an opposing object. An irradiation unit irradiates light onto the object. A reflected light intensity measurement unit measures the intensities of the reflected light that has been irradiated by the irradiation unit and reflected from each position on the object. An object determination unit determines whether the object is covered by a translucent container based on the distances measured by the distance measurement unit and the reflected light intensities measured by the reflected light intensity measurement unit.

Abstract: An image collation unit determines whether input image data matches pre-registered image data or a feature quantity of the input image data matches a pre-registered feature quantity of the image data, and stores in a memory at least one of input image data which is determined to match and information which represents the input image data. A complexity computing unit computes complexity of the image data. An image flatness determination unit determines, on the basis of the computed complexity of the image data, whether the image data is data which denotes a flat image. An information processing execution unit executes, when it is determined that newly input image data is data which denotes a flat image and the input image data or the information which represents the input image data is stored in the memory, information processing specified by the input image data and the like stored in the memory.

Abstract: An image comparison unit (81) compares a query image with a registered image to detect, in the registered image, a region corresponding to the query image. An action information determining unit (82), on the basis of intermediate information in which sub-region information identifying sub-regions in the registered image and action information representing information processing to be executed by a target device are associated with each other, identifies sub-regions on the basis of the sub-region information, chooses a sub-region having the highest degree of matching with the detected region among the identified sub-regions, and identifies action information corresponding to the chosen sub-region. An action information execution unit (83) causes the target device to execute information processing corresponding to the action information.

Abstract: An image processing device compares multiple images capturing a detection target accumulated at a bottom surface of a transparent container or a detection target accumulated at a surface at which a medium enclosed inside a transparent container contacts another medium inside the transparent container, the images being captured while rotating the transparent container, to determine candidate regions that move in a movement direction in accordance with the rotation, the image processing device determines the presence or absence of the detection target by using first determination results obtained by using a first learning model and image information for the candidate regions to determine whether or not the candidate regions are the detection target, and second determination results obtained by using a second learning model and information indicating a chronological change in the candidate regions to determine whether or not the candidate regions are the detection target.

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.
