1. An image recognition system for detecting and tracking at least an image portion associated with a predefined object from a moving picture, wherein the image recognition system is configured to be able to perform: an object detection processing step of detecting the object from the moving picture; a tracking point specification processing step of specifying at least a predetermined point associated with the object as a tracking point; a tracking target recognition processing step of recognizing an actual tracking target based on the tracking point; a tracking processing step of tracking the tracking target; and a determination processing step of determining the type of the tracking target's behavior based on a result of the tracking processing step, and the tracking point specification processing step and the determination processing step are implemented by software, while the object detection processing step, the tracking target recognition processing step, and the tracking processing step are implemented by hardware.
