Methods and apparatus to count people in images
First Claim
Patent Images
1. A method to count people, comprising:
- capturing an image of a body region in a first frame;
when a second frame different from the first frame includes the image of the body region, incrementing a first count of persons in the second frame; and
counting a number of faces in the second frame to form a second count.

8. An apparatus to count people, comprising:
-
a face detector to detect faces in a first frame and to increment a face tally associated with the first frame based on a number of faces detected in the first frame; a body image capturer to collect an image of a body region adjacent to a detected face from a second frame different from the first frame; and a comparator to compare image data of the first frame to the image of the body region from the second frame, and to increment a body region count associated with the first frame when the image data of the first frame matches the image of the body region from the second frame, wherein at least one of the face detector, the body image capturer, or the comparator is implemented via a logic circuit. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A tangible computer readable medium comprising instructions that, when executed, cause a machine to at least:
-
detect a first face in a first frame corresponding to a first time; capture an image of a region adjacent the first face in the first frame, the region being at a first position within the first frame; determine whether a second frame corresponding to a second time includes the image at the first position; and increment a people tally associated with the second frame when the second frame includes the image at the first position and the detected face of the first frame is not detected in the second frame. - View Dependent Claims (16, 17, 18)
