中文说明：该示例使用两组模板—一组用于检测，另一组用于识别。
English Description：
The example uses two set of templates - one for detection and the other for recognition. To save computation, the detection templates are low resolution, and the example uses one detection template per sign. Also, because the red pixels are the distinguishing feature of the traffic warning signs, the example uses these pixels in the detection step.
