Abstract

Being able to detect humans in crowds is of great interest as such detection of humans may be used for counting and other crowd analyses, such as crowd density, crowd formation and crowd dispersion. Disclosed are methods, devices and systems for detecting human objects in a video. The method includes determining pixels of a video image are foreground pixels, the a group of the foreground pixels constituting a foreground blob set of one or more foreground blobs. The method then compares, for each of N predetermined shapes at corresponding ones of N predetermined locations within the video image, the corresponding predetermined shape with the foreground blob set to obtain a corresponding probability of a human at the corresponding predetermined location, thereby obtaining N probabilities corresponding to the N locations. The method then uses the N probabilities to determine X humans are represented by the foreground blob set.
