METHODS AND APPARATUS TO COUNT PEOPLE IN IMAGES

Example apparatus disclosed herein include an analyzer to determine whether a first face rectangle is located in an overlap region of an image frame pair including a first image frame obtained from a first image sensor and a second image frame obtained from a second image sensor, the first face rectangle associated with the first image frame. Disclosed example apparatus also include a comparator to determine whether the first face rectangle is redundant to a second face rectangle when the first face rectangle is located in the overlap region of the image frame pair. Disclosed example apparatus further include an overlap eliminator to link first coordinates of the first face rectangle and second coordinates of the second face rectangle in a correlated face history when the first face rectangle is redundant to the second face rectangle, the correlated face history to identify redundant face rectangles in subsequent image frame pairs.
