查找图像中的单色，水平空间 [英] Find single color, horizontal spaces in image

问题描述

例如，可能有一个表格，其中的行成行.我怎样才能找到所有穿过桌子的直线，水平线?例如. (红线是找到的线):

For example, there might be a table with text in rows. How could I find all straight, horizontal lines going through the table? E.g. (red lines are the found lines):

推荐答案

只需for this question，要检测horizontal lines，morph-op就足够了.

Just for this question, to detect the horizontal lines, the morph-op is enough.

import cv2 
img = cv2.imread("test.jpg")
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
kernel = np.ones((1,100), np.uint8)
morphed = cv2.morphologyEx(gray, cv2.MORPH_CLOSE, kernel)
cv2.imshow("res", morphed);cv2.waitKey();cv2.destroyAllWindows()

更新，类似的问题:

(1)在图像中查找单色水平空间

(2) OpenCV/cv2:删除水平下划线
