Abstract
Methods and apparatus to count people in images are disclosed. An example method includes, in response to determining that a first person indication of a first frame obtained via a first image sensor is redundant to a second person indication of a second frame obtained via a second image sensor, storing a first coordinate of the first person indication in connection with a second coordinate of the second person indication in a database; and in response to detecting a third person indication in a third frame obtained via the first image sensor, querying the database with a third coordinate of the third person indication to determine whether the third coordinate matches the first coordinate.
Claims20
A method, comprising:
- in response to determining that a first person indication of a first frame obtained via a first image sensor is redundant to a second person indication of a second frame obtained via a second image sensor, storing a first coordinate of the first person indication in connection with a second coordinate of the second person indication in a database;
- and
- in response to detecting a third person indication in a third frame obtained via the first image sensor, querying the database with a third coordinate of the third person indication to determine whether the third coordinate matches the first coordinate.
A tangible machine readable storage medium comprising instructions that, when executed, cause a machine to at least:
- in response to determining that a first person indication of a first frame obtained via a first image sensor is redundant to a second person indication of a second frame obtained via a second image sensor, store a first coordinate of the first person indication in connection with a second coordinate of the second person indication in a database;
- in response to detecting a third person indication in a third frame obtained via the first image sensor, query the database with a third coordinate of the third person indication to determine whether the third coordinate matches the first coordinate.
An apparatus, comprising:
- a database to store a first coordinate of a first person indication of a first frame in connection with a second coordinate of a second person indication of a second frame, the first person indication obtained via a first image sensor being redundant to the second person indication obtained via a second image sensor;
- and
- a searcher to, in response to detecting a third person indication in a third frame obtained via the first image sensor, query the database with a third coordinate of the third person indication to determine whether the third coordinate matches the first coordinate.
