matlab手写文本行分割,将手写文本分割成行

示例图像

我使用的代码基于stackoverflow上的一个类似问题，但是由于一些字符接触，它不能正常工作。代码如下：import cv2

import numpy as np

#import image

image = cv2.imread('form1.jpg')

#cv2.imshow('orig',image)

#cv2.waitKey(0)

#grayscale

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

cv2.imshow('gray',gray)

cv2.waitKey(0)

#binary

ret,thresh = cv2.threshold(gray,127,255,cv2.THRESH_BINARY_INV)

cv2.imshow('second',thresh)

cv2.waitKey(0)

#dilation

kernel = np.ones((5,100), np.uint8)

img_dilation = cv2.dilate(thresh, kernel, iterations=1)

cv2.imshow('dilated',img_dilation)

cv2.waitKey(0)

#find contours

im2,ctrs, hier = cv2.findContours(img_dilation.copy(), cv2.RETR_EXTERNAL,

cv2.CHAIN_APPROX_SIMPLE)

#sort contours

sorted_ctrs = sorted(ctrs, key=lambda ctr: cv2.boundingRect(ctr)[0])

for i, ctr in enumerate(sorted_ctrs):

# Get bounding box

x, y, w, h = cv2.boundingRect(ctr)

# Getting ROI

roi = image[y:y+h, x:x+w]

# show ROI

cv2.imshow('segment no:'+str(i),roi)

cv2.rectangle(image,(x,y),( x + w, y + h ),(90,0,255),2)

cv2.waitKey(0)

cv2.imshow('marked areas',image)

cv2.waitKey(0)

我怎样才能让它在某些字符重叠的情况下正确地分割行？在
