METHOD FOR AUTOMATIC DETECTION AND TRACKING OF MULTIPLE TARGETS WITH MULTIPLE CAMERAS AND SYSTEM THEREFOR
First Claim
1. A method of multi-target detecting and tracking with multiple cameras, comprising the steps of:
- (a) analyzing a detection result of a plurality of camera views using a target detection algorithm to generate a plurality of analysis data;
(b) integrating the analysis data with a Baysian framework to create a target detection probability (TDP) distribution; and
(c) simultaneously and automatically detecting and tracking a plurality of moving targets in the camera views.

Abstract
A method for automatically detecting and tracking multiple targets in a multi-camera surveillance zone and system thereof. In each camera view of the system only a simple object detection algorithm is needed. The detection results from multiple cameras are fused into a posterior distribution, named TDP, based on the Bayesian rule. This TDP distribution represents a likelihood of presence of some moving targets on the ground plane. To properly handle the tracking of multiple moving targets with time, a sample-based framework which combines Markov Chain Monte carlo (MCMC), Sequential Monte Carlo (SMC), and Mean-Shift Clustering, is provided. The detection and tracking accuracy is evaluated by both synthesized videos and real videos. The experimental results show that this method and system can accurately track a varying number of targets.

7. A system of multi-target detecting and tracking with multiple cameras, comprising:
-
a detection analyzing means for analyzing a plurality of camera views using a target detection algorithm to generate a plurality of analysis data; a Bayesian framework for integrating the analysis data to form a TDP distribution so as to detect any newly appearing target and provide temporal information in a time domain between successive frames; and a tracking means for automatically detecting and tracking a plurality of moving targets in the camera views and converting the detecting and tracking into a sample management process. - View Dependent Claims (8, 9, 10, 11, 12)
