People counting device, people counting method and people counting program
First Claim
1. A people counting device comprising:
- a person presence region extractor which extracts a region in which a person is present by performing person detection in relation to an input image;
a person presence state estimator which estimates a person presence state from an extraction result of the person presence region extractor, the person presence state estimator estimates a direction in which persons are overlapping based upon the extraction result of the person presence region extractor;
a portion detector selector which selects a type of portion detector to be used for people count measurement based on an estimation result of the person presence state estimator, and outputs portion detector information;
a portion detection processor which performs a portion detection process for detecting a portion of a person based on the portion detector information output from the portion detector selector; and
a people counter which obtains a number of people within the input image from a portion detection process result of the portion detection processor.

Abstract
A people counting device includes: a person presence region extraction unit which extracts a region in which a person is present by performing person detection in relation to an input image; a person presence state estimation unit which estimates a person presence state from an extraction result; a portion detector selection unit which selects a type of portion detector to be used for people count measurement based on the estimation result, and outputs portion detector information. The people counting device further includes: a portion detection process unit which performs a portion detection process for detecting a portion of a person based on the portion detector information; and a people counting unit which obtains a number of people within the input image from a portion detection process result.

6. A people counting method comprising:
-
extracting a region in which a person is present by performing person detection in relation to an input image; estimating a person presence state from a result in which a region where a person is present is extracted, the estimating estimates a direction in which persons are overlapping based upon the extraction result of the extracting; selecting a type of portion detector to be used for people count measurement based on a result in which a person presence state is estimated, and outputting portion detector information; performing, by a processor, a portion detection process for detecting a portion of a person based on the portion detector information of the selected portion detector; and obtaining a number of people within the input image from a result of the detection process. - View Dependent Claims (8, 9, 10, 11, 17)

7. A non-transitory computer readable storage medium storing a people counting program, the people counting program comprising instructions, which, when executed by a computer, cause the computer to:
-
extract a region in which a person is present by performing person detection in relation to an input image; estimate a person presence state from a result in which a region where a person is present is extracted, by estimating a direction in which persons are overlapping based upon the extraction result of the extracting a region; select a type of portion detector to be used for people count measurement based on a result in which a person presence state is estimated, and outputting portion detector information; perform a portion detection process for detecting a portion of a person based on the portion detector information of the selected portion detector; and obtain a number of people within the input image from a result of the detection process. - View Dependent Claims (12, 13, 14, 15, 18)
