我正在做一个关于图像处理的大学课程项目。这是我的原图：

我想在单个文本行图像上加入附近/重叠的边界框，但我不知道如何。到目前为止，我的代码看起来像这样（感谢@HansHirse 的帮助）：

import os
import cv2
import numpy as np
from scipy import stats
image = cv2.imread('example.png')

gray = cv2.cvtColor(image,cv2.COLOR_BGR2GRAY)
ret,thresh = cv2.threshold(gray,127,255,cv2.THRESH_BINARY_INV+cv2.THRESH_OTSU)

#dilation
kernel = np.ones((5,5), np.uint8)
img_dilation = cv2.dilate(thresh, kernel, iterations=1)

#find contours
ctrs, hier = cv2.findContours(img_dilation.copy(), cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)

def sort_contours(cnts, method="left-to-right"):
    # initialize the reverse flag and sort index
    reverse = False
    i = 0

    # handle if we need to sort in reverse
    if method == "right-to-left" or method == "bottom-to-top":
        reverse = …
