中文说明：这个程序是基于Matlab的实时交通标志识别。首先，通过摄像头捕捉到的图像实时。其次，将图像二值化后进行预处理所收集的图像（筛选）。然后，由颜色划分的目标区域特点.Lastly，计算SIFT特征和匹配模板来实现交通标志识别的目标区域。
English Description：
This program is a real-time traffic sign recognition based on matlab. Firstly, through the camera to capture images real time.Secondly, pretreat the collected images (filtering).Then after the image binarization, divided the target area by the color characteristics .Lastly, calculate SIFT feature and match the target area with templates to achieve traffic sign recognition.
