//cvThreshold（）函數功能：采用Canny方法對圖像進行邊緣檢測
//函數原型：
//void?cvThreshold（?//函數說明：
//const?CvArr*?src			//第一個參數表示輸入圖像，必須為單通道灰度圖。
//CvArr*?dst			//第二個參數表示輸出的邊緣圖像，為單通道黑白圖。
//double?threshold			//第三個參數表示閾值
//double?max_value			//第四個參數表示最大值。
//int?threshold_type			//第五個參數表示運算方法。
//）;
//在OpenCV的imgproc\types_c.h中可以找到運算方法的定義。
