对图像进行边缘检测python版本： # coding=gbk import cv2 img = cv2 . imread ( "1.jpg" , 0 ) x = cv2 . Sobel ( img , cv2 . CV_16S , 1 , 0 ) y = cv2 . Sobel ( img , cv2 . CV_16S , 0 , 1 ) absX = cv2 . convertScaleAbs ( x ) # 转回u
对图像进行边缘检测python版本：
import cv2
img = cv2.imread("1.jpg", 0)
x = cv2.Sobel(img,cv2.CV_16S,1,0)
y = cv2.Sobel(img,cv2.CV_16S,0,1)
absX = cv2.convertScaleAbs(x) # 转回uint8
absY = cv2.convertScaleAbs(y)
dst = cv2.addWeighted(absX,0.5,absY,0.5,0)
cv2.imshow("Result", dst)
cv2.waitKey(0)
cv2.destroyAllWindows()
运行如下：
