Abstract
A method for performing crowd segmentation includes receiving video image data (S). Background differencing is performed on the received video image data to identify a foreground silhouette shape (S). Approximate number and position of human subjects within the received video image data are determined by matching the foreground silhouette shape against a set of predetermined foreground silhouette shapes, for each of which a number and position of human subjects is known (S). The estimated number and position of the human subjects is refined to determine a final number and position of the human subjects (S).
