first exemplary embodiment

[0035]First, the outline of this exemplary embodiment will be described. An analysis apparatus according to this exemplary embodiment analyzes video data to extract a person. Then, the analysis apparatus calculates the time period (continuous appearance time period) for which the extracted person has been continuously present in a predetermined area and the time interval (reappearance time interval) until the extracted person reappears in the predetermined area after leaving the predetermined area (disappearing from the predetermined area) for each extracted person. Then, the analysis apparatus infers the characteristic of the extracted person on the basis of the continuous appearance time period and the reappearance time interval. The characteristic of the extracted person inferred on the basis of the continuous appearance time period and the reappearance time interval is a kind of information that can be recognized from context or the state of the person. Examples of the character...

second exemplary embodiment

[0098]An analysis apparatus 10 according to this exemplary embodiment stores the personal characteristic inferred by the method described in the first exemplary embodiment in association with each person. In a case in which a certain person appears repeatedly in a predetermined area, the analysis apparatus 10 calculates the continuous appearance time period and the reappearance time interval whenever the person appears. On all such occasion, on the basis of the calculation result, a personal characteristic is inferred. On the basis of the inference result, the analysis apparatus 10 counts the number of times each personal characteristic is inferred, for each person. Then, the analysis apparatus 10 calculates the reliability of each inferred personal characteristic on the basis of the number of counts. Hereinafter, this exemplary embodiment will be described in detail.

third exemplary embodiment

[0108]An analysis apparatus 10 according to this exemplary embodiment provides a function of setting correspondence information in which a pair of the continuous appearance time period and the reappearance time interval is associated with a personal characteristic.

[0109]FIG. 14 illustrates an example of the functional block diagram of the analysis apparatus 10 according to this exemplary embodiment. As illustrated in FIG. 14, the analysis apparatus 10 includes a person extraction unit 11, a time calculation unit 12, an inference unit 13, and a setting unit 16. The analysis apparatus 10 may further include a count unit 14, a reliability calculation unit 15, a notification unit, a storage unit, and an output unit, which are not illustrated in FIG. 14. The person extraction unit 11, the time calculation unit 12, the count unit 14, the reliability calculation unit 15, the notification unit, the storage unit, and the output unit have the same structure as those in the first and second ex...

Abstract

Provided is an analysis apparatus (10) including a person extraction unit (11) that analyzes video data to extract a person, a time calculation unit (12) that calculates a continuous appearance time period for which the extracted person has been continuously present in a predetermined area and a reappearance time interval until the extracted person reappears in the predetermined area for each extracted person, and an inference unit (13) that infers a characteristic of the extracted person on the basis of the continuous appearance time period and the reappearance time interval.

Description

[0001]The present application is a Continuation application of U.S. patent application Ser. No. 16 / 080,745 filed on Aug. 29, 2018, which is a National Stage Entry of international application PCT / JP2017 / 005100, filed Feb. 13, 2017, which claims the benefit of priority from Japanese Patent Application 2016-067538 filed on Mar. 30, 2016, the disclosures of all of which are incorporated herein, in their entirety, by this reference.TECHNICAL FIELD[0002]The invention relates to an analysis apparatus, an analysis method, and a program.BACKGROUND ART[0003]The related art is disclosed in Patent Document 1. The Patent Document 1 discloses a countermeasure system against suspicious persons which detects the face of a person in a captured image of a scene in a surveillance range and determines whether countermeasures are needed or the degree of countermeasures on the basis of, for example, the size of the face, the time for which the person has been continuously present in the surveillance ran...
