First Claim
Patent Images
1. A method for object tracking in a surveillance area, the method comprising the steps of:
- eliminating the background and identifying foreground regions using color models in compressed and uncompressed domains;
identifying one or more objects of interest (OOI) in low resolution, high occlusion levels;
selecting an appropriate detection and tracking algorithm based on an estimated congestion level and an estimated occlusion level;
detecting a group OOI;
tracking the group OOI in low resolution, high occlusion levels;
analyzing the surveillance area in low resolution, high occlusion levels; and
identifying one or more individual OOIs.

Abstract
Embodiments of the invention relate to methods and systems for providing real-time video surveillance of crowded environments. The method consists of several object detection and tracking processes that may be selected automatically to track individual objects or group of objects based on the resolution and occlusion levels in the input videos. Possible objects of interest (OOI) may be human, animals, cars etc. The invention may be used for tracking people in crowded environments or cars in heavy traffic conditions.
