Abstract
Example apparatus disclosed herein includes a grouper to generate a first presence indication based on a threshold number of segments of image data including patterns of light values corresponding to a first human pulse. Disclosed example apparatus also include a face identifier to identify a first location associated with a human face in an environment associated with the image data based on thermal imaging data from a thermal imaging device, and output the first location associated with the human face in the environment associated with the image data.
Claims20
A computing system comprising a processor and a memory, the computing system configured to perform a set of acts comprising:
- obtaining light information for respective segments of a plurality of segments of a media exposure environment for a time period;
- determining that the light information for a threshold number of neighboring segments of the plurality of segments is indicative of a same pulse pattern and exhibits synchronicity;
- based on the determining, detecting that a person is present in the media exposure environment at the time period;
- detecting presentation of media in the media exposure environment during the time period;
- storing an indication of the detection of the person;
- and
- storing media identifying information for the media.
A method comprising:
- obtaining light information for respective segments of a plurality of segments of a media exposure environment for a time period;
- determining that the light information for a threshold number of neighboring segments of the plurality of segments is indicative of a same pulse pattern and exhibits synchronicity;
- based on the determining, detect that a person is present in the media exposure environment at the time period;
- detecting presentation of media in the media exposure environment during the time period;
- storing an indication of the detecting of the person;
- and
- storing media identifying information for the media.
A non-transitory computer-readable medium having stored therein instructions that, upon execution by a computing system, cause the computing system to perform a set of acts comprising:
- obtaining light information for respective segments of a plurality of segments of a media exposure environment for a time period;
- determining that the light information for a threshold number of neighboring segments of the plurality of segments is indicative of a same pulse pattern and exhibits synchronicity;
- based on the determining, detecting that a person is present in the media exposure environment at the time period;
- detecting presentation of media in the media exposure environment during the time period;
- storing an indication of the detecting of the person;
- and
- storing media identifying information for the media.
