Abstract

Methods and apparatus to count people appearing in an image (12) are disclosed. One disclosed method reduces objects appearing in a series of images to one or more blobs; for each individual image in a set of the images of the series of images, represents the one or more blobs (190); in the individual image by one or more symbols in a histogram (278); and analyzes the symbols appearing in the histogram to count the people in the image.
