3D HUMAN POSE AND SHAPE MODELING
First Claim
Patent Images
1. A method of detecting human objects in a video, comprising:
- determining pixels of a video image are foreground pixels, the group of foreground pixels constituting a foreground blob set of one or more foreground blobs;
for each of N locations within the video image, where N is an integer, comparing a predetermined shape with the foreground blob set to obtain a corresponding probability of a human at the location, thereby obtaining N probabilities corresponding to the N locations;
using the N probabilities, determining X humans are represented by the foreground blob set, where X is whole number.

Abstract
Methods, devices and systems for performing video content analysis to detect humans or other objects of interest a video image is disclosed. The detection of humans may be used to count a number of humans, to determine a location of each human and/or perform crowd analyses of monitored areas.

24. A method of detecting human objects in a video, comprising:
-
determining pixels of a video image of a real world scene are foreground pixels, the group of foreground pixels constituting a foreground blob set of one or more foreground blobs; for each of N locations within the video image, where N is an integer, comparing a predetermined shape with the foreground blob set to determine X humans are represented by the foreground blob set, where X is whole number and a location of each of the X humans is determined as a location within a horizontal plane of the real world. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32)
