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.
Claims9
An analysis apparatus comprising
- a memory storing instructions;
- and
- at least one processor executing the instructions to perform:
- extracting a person from a video data;
- calculating a time period for which the extracted person has been continuously present in a predetermined area and a time interval between first point in time when the extracted person disappears from the predetermined area and second point in time when the extracted person reappears to the predetermined area;
- inferring one or more personal characteristics that may be corresponding to the extracted person based on the calculated time period and the calculated time interval;
- calculating probability that the person is corresponding to each personal characteristic;
- and
- outputting information based on the probability.
An analysis method performed by a computer, the method comprising:
- extracting a person from a video data;
- calculating a time period for which the extracted person has been continuously present in a predetermined area and a time interval between first point in time when the extracted person disappears from the predetermined area and second point in time when the extracted person reappears to the predetermined area;
- inferring one or more personal characteristics that may be corresponding to the extracted person based on the calculated time period and the calculated time interval;
- calculating probability that the person is corresponding to each personal characteristic;
- and
- outputting information based on the probability.
A non-transitory computer readable recording medium storing programs, the programs causing a computer to perform:
- extracting a person from a video data;
- calculating a time period for which the extracted person has been continuously present in a predetermined area and a time interval between first point in time when the extracted person disappears from the predetermined area and second point in time when the extracted person reappears to the predetermined area;
- inferring one or more personal characteristics that may be corresponding to the extracted person based on the calculated time period and the calculated time interval;
- calculating probability that the person is corresponding to each personal characteristic;
- and
- outputting information based on the probability.
