【图像识别与处理】边缘检测网络

1 边缘检测算子

import cv2
import numpy as np  
img = cv2.imread("./image.jpg", 0)
x = cv2.Sobel(img,cv2.CV_16S,1,0)
y = cv2.Sobel(img,cv2.CV_16S,0,1)
absX = cv2.convertScaleAbs(x)
absY = cv2.convertScaleAbs(y)
dst = cv2.addWeighted(absX,0.5,absY,0.5,0)
cv2.imshow("absX", absX)
cv2.imshow("absY", absY)
cv2.imshow("Result", dst)
cv2.waitKey(0) 
cv2.destroyAllWindows()
