Visual detection and tracking algorithms for human motion.

In dense scenes, a large number of individuals can introduce serious complications for motion detection, such as blurred vision, chaotic scenes, and complex behaviours. For low-density pedestrian detection and tracking algorithms, the accuracy is greatly reduced for both detection and tracking. High-density detection or tracking fails too when these problems are encountered in high-density scenes. In light of the above problems, a detection algorithm and a tracking algorithm based on the human head and shoulder model are proposed. A support vector machine is used to train the classifier by machine learning. The detection algorithm proposed in this paper achieves a detection accuracy of 94% by using the MIT and INRIA datasets. The average accuracy of pedestrian tracking in high-density scenes is approximately 95%. [ABSTRACT FROM AUTHOR]
