Methods and apparatus for detecting a composition of an audience of an information presenting device
View Patent ↗Methods and apparatus for detecting a composition of an audience of an information presenting device are disclosed. A disclosed example method includes: capturing at least one image of the audience; determining a number of people within the at least one image; prompting the audience to identify its members if a change in the number of people is detected based on the number of people determined to be within the at least one image; and if a number of members identified by the audience is different from the determined number of people after a predetermined number of prompts of the audience, adjusting a value to avoid excessive prompting of the audience.
1. A method, comprising:
performing a first comparison of a first number of people appearing in a first image of an environment and a first amount of audience member inputs received from the environment;
calculating a count of unidentified people in the environment based on the first comparison;
performing a second comparison of a second number of people appearing in a second image and a second amount of audience member inputs received from the environment, the second image captured after the first image; and
adjusting a result of the second comparison by the count of unidentified people.
2. A method as defined in claim 1 , further comprising performing the first comparison in response to the first number of people differing from a third number of people identified in a third image captured before the first image.
3. A method as defined in claim 1 , further comprising calculating the count of unidentified people based on the first comparison in response to persistently detecting a difference between multiple prior numbers of people appearing in images and multiple prior audience member inputs, respectively.
4. A method as defined in claim 3 , wherein persistently detecting the difference comprises sequentially detecting a difference between the multiple prior numbers of people appearing in images and multiple prior audience member inputs more than a threshold number of times.
5. A method as defined in claim 1 , wherein adjusting the result of the second comparison comprises increasing a value associated with the second comparison by the count of unidentified people.
6. A method as defined in claim 1 , further comprising associating the count of unidentified people with media detected in parallel with capture of the first image.
7. A method as defined in claim 1 , wherein the audience member inputs are received in response to prompts generated when the first number of people differs from a third number of people identified in a third image captured before the first image.
8. A tangible machine readable storage device or storage disc comprising instructions that, when executed, cause a machine to at least:
perform a first comparison of a first number of people identified in a first image of an environment and an amount of audience member inputs received from the environment;
calculate a count of unidentified people in the environment based on the first comparison; and
factor the count of unidentified people into a second comparison of the first image to a second image captured after the first image.
9. A storage device or storage disc as defined in claim 8 , wherein the instructions cause the machine to perform the first comparison in response to the first number of people differing from a second number of people identified in a third image captured before the first image.
10. A storage device or storage disc as defined in claim 8 , wherein the instructions cause the machine to calculate the count of unidentified people based on the first comparison in response to detecting a persistent difference between image analysis results and the audience member inputs.
11. A storage device or storage disc as defined in claim 10 , wherein the instructions cause the machine to detect the persistent difference by detecting a threshold number of sequential differences between the image analysis results and the audience member inputs.
12. A storage device or storage disc as defined in claim 8 , wherein the instructions cause the machine to factor the count of unidentified people into the second comparison by increasing a value associated with the first image using the count of unidentified people.
13. A storage device or storage disc as defined in claim 8 , wherein the instructions cause the machine to associate the count of unidentified people with media identifying data detected in connection with the first image.
14. A storage device or storage disc as defined in claim 8 , wherein the audience member inputs are received in response to prompts generated when the first number of people differs from a second number of people identified in a third image captured before the first image.
15. An apparatus, comprising:
a memory storing machine readable instructions; and
a processor to execute the instructions to:
perform a first comparison of a first number of people identified in a first image of an environment and a first amount of audience member inputs received from the environment;
calculate a count of unidentified people in the environment based on the first comparison;
perform a second comparison of a second number of people appearing in a second image and a second amount of audience member inputs received from the environment, the second image captured after the first image; and
adjust a result of the second comparison by the count of unidentified people.
16. An apparatus as defined in claim 15 , wherein the processor is to perform the first comparison in response to the first number of people differing from a third number of people identified in a third image captured before the first image.
17. An apparatus as defined in claim 15 , wherein the processor is to calculate the count of unidentified people based on the first comparison in response to persistently detecting a difference between multiple prior numbers of people appearing in images and multiple prior audience member inputs, respectively.
18. An apparatus as defined in claim 17 , wherein persistently detecting a difference comprises sequentially detecting a difference between the multiple prior numbers of people appearing in images and the multiple prior audience member inputs more than a threshold number of times.
19. An apparatus as defined in claim 15 , wherein the processor is to adjust the result of the second comparison by increasing a value associated with the second comparison by the count of unidentified people.
20. An apparatus as defined in claim 15 , wherein the processor is to associate the count of unidentified people with media detected in parallel with capture of the first image.
