- Segmenting image files with text (and pictures) into blocks
Here is a different way to do that with Python OpenCV Apply morphology dilate with horizontal kernel longer than letter spacing and then smaller vertical kernel to remove thin horizontal lines remaining from line in page x,y,w,h = cv2 boundingRect(c) cv2 rectangle(result, (x, y), (x+w, y+h), (0, 0, 255), 2)
