Abstract: A control apparatus (2000) computes a waiting time index value for each of a plurality of gates (20) for entering an area (10). The control apparatus (2000) detects, from among the plurality of gates (20), a first gate (20) and a second gate (20) of which relation between the waiting time index values satisfies a first criterion. Herein, the waiting time index value of the first gate (20) is greater than the waiting time index value of the second gate (20). The control apparatus (2000) causes a terminal (30) associated with the first gate (20) to output priority use information, which allows prioritized use of the second gate (20).

Abstract: To improve efficiency of road surveillance, a road surveillance system includes a detection unit 122 and a processing unit 134. The detection unit 122 detects a road state being a state of an object on a road by processing an image in which the road is captured. The processing unit 134 performs, when the road state satisfies a first criterion, any of notification processing of making a notification of the road state that satisfies the first criterion according to notification setting related to the notification, and change-related processing related to a change in the notification setting, based on whether a second criterion is satisfied. The second criterion is a criterion related to a determination result of whether the road state satisfies the first criterion.

Abstract: An image processing apparatus (10) includes an image processing unit (110) and a risk information generation unit (120). The image processing unit (110) acquires and processes an image generated by an image capture apparatus (20), that is, an image including a plurality of persons. As an example, the image processing unit (110) sets a person being at least part of the plurality of persons as a reference person and computes a distance (first distance) between the reference person and the closest person to the reference person. By using the first distance, the risk information generation unit (120) generates infection risk information in a target region being an image capture target of the image capture apparatus (20).

Abstract: In a video decoding device, a quantization step size decoding unit calculates a quantization step size that controls a granularity of the inverse quantization by, based on an image prediction, selectively using a mean value of at least a quantization step size assigned to a leftwardly adjacent neighboring image block already decoded and a quantization step size assigned to a upwardly adjacent neighboring image block already decoded or a quantization step size assigned to an image block decoded immediately before.

Abstract: A label feature extraction means 71 extracts, from reference information, a label feature that is a vector representing a feature of the reference information. A label feature dimension reduction means 72 performs dimension reduction of the label feature. An image feature extraction means 73 extracts an image feature from a target image that is an image in which an object to be recognized is captured. A feature transformation means 74 performs feature transformation on the image feature in such a manner that comparison with the label feature after the dimension reduction becomes possible. The class recognition means 75 recognizes a class of the object to be recognized by comparing the image feature after the feature transformation with the label feature after the dimension reduction.
