Python OpenCV去除字母后面的杂线操作

原图 代码 src = cv2.imread("28.png") gray_src = cv2.cvtColor(src, cv2.COLOR_BGR2GRAY) #cv2.imshow("input image", src) #cv2.imshow("gray image", gray_src) #cv2.waitKey(0) gray_src = cv2.bitwise_not(gray_src) #二值化 binary_src = cv2.adaptiveThreshold(gray_src, 255, cv2.ADAPTIVE_THRESH_MEAN
