在使用OpenCV的python中，在景观图像的每一行文本的上方和下方放置一条线，或在图像中的文本上方放置多个方框，而不会丢失其分辨率

import cv2
import numpy as np

image = cv2.imread('image.jpg')

gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)

_, binary = cv2.threshold(gray, 127, 255, cv2.THRESH_BINARY)

kernel = np.ones((5, 5), np.uint8)
dilated = cv2.dilate(binary, kernel, iterations=3)
contours, _ = cv2.findContours(dilated, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)

for contour in contours:
    x, y, w, h = cv2.boundingRect(contour)
    cv2.line(image, (x, y), (x + w, y), (0, 255, 0), 2)  # 在文本上方放置一条线
    # 或者使用下面的代码在文本上方放置一个方框
    # cv2.rectangle(image, (x, y - 10), (x + w, y + h), (0, 255, 0), 2)

cv2.imshow('Result', image)
cv2.waitKey(0)
cv2.destroyAllWindows()
