Abstract: The present invention provides a learning apparatus (10) including: an acquisition unit (11) that acquires an image; a similarity computation unit (12) that computes a similarity between the acquired image, and a first image being accumulated in advance and indicating an abnormal state; a registration unit (13) that registers, as a second image indicating a normal state, the acquired image whose similarity is equal to or less than a first reference value; and a learning unit (14) that generates an estimation model for discriminating between normal and abnormal by machine learning using the first image and the second image.

Abstract: The analysis apparatus (2000) includes a co-appearance event extraction unit (2020) and a frequent event detection unit (2040). The co-appearance event extraction unit (2020) extracts co-appearance events of two or more persons from each of a plurality of sub video frame sequences. The sub video frame sequence is included in a video frame sequence. The analysis apparatus (2000) may obtain the plurality of sub video frame sequences from one or more of the video frame sequences. The one or more of the video frame sequences may be generated by one or more of surveillance cameras. Each of the sub video frame sequences has a predetermined time length. The frequent event detection unit (2040) detects co-appearance events of the same persons occurring at a frequency higher than or equal to a pre-determined frequency threshold.

Abstract: A server (20) stores person information in which a feature of an appearance and a feature of a motion of a person extracted from a video are associated with each other, searches for the person information using input information received from a terminal apparatus (10) as a key, and returns a search result to the terminal apparatus (10). The terminal apparatus (10) acquires and stores a part or a whole of the person information stored in the server (20) from the server (20), performs a search using the input information as a key, and displays the search result on a display as a candidate of information to be input in an input field.

Abstract: An acquisition unit (2020) acquires a combination of person information and transaction information for a first transaction. The person information is information representing a person who executes a transaction. The transaction information is various kinds of information regarding the transaction. A storage device (10) stores transaction information of each transaction. Using the person information of the first transaction acquired by the acquisition unit (2020), a detection unit (2040) acquires transaction information of a transaction (second transaction), which is executed by a person having a high degree of similarity with a person who executes the first transaction, from the storage device (10). The detection unit (2040) detects an abnormal transaction using the transaction information of the first transaction and the transaction information of the second transaction.
