1.对原图像高斯平滑 　　2.对高斯平滑后的图像进行sobel边缘检测。这里需要求横的和竖的还有联合的，所以一共三个需要sobel边缘检测图像。 　　3.对联合的sobel检测图像进行非极大抑制 　　4.连接边缘点并进行滞后阈值处理。 (1. Gaussian smoothing the original image 2. Gaussian smoothed image was sobel edge detection. Here and there on request transverse vertical joint, so a total of three required sobel edge detection image. 3. sobel joint detection image greatly inhibit non- 4. Connect the edge point and hysteresis thresholding.)
