python实现图片中文字分割效果

本文实例为大家分享了python实现图片中文字分割的具体代码，供大家参考，具体内容如下

1、原始图片（包含数字）：

结果图：

2、原始图片（包含文字）：

结果图：

3、代码如下：

import cv2
import numpy as np

path = 'test.jpg'
root = 'output\\'
# 图像resize
dsize = 36
img = cv2.imread(path)
data = np.array(img)
height = data.shape[0]
width = data.shape[1]
# 设置最小的文字像素高度
min_val = 10

start_i = -1
end_i = -1
# 存放每行的起止坐标
rowinfo = []

# 行分割
for i in range(height):

# 行中有字相关信息
if (not data[i].all()):
end_i = i
if(start_i < 0):
start_i = i
pass
# 行中无字相关信息
elif (data[i].all() and start_i >= 0):
if(end_i - start_i >= min_val):
rowinfo.append((start_i, end_i))
pass
start_i, end_i = -1, -1
print(rowinfo)

# 列分割
start_j = -1
end_j = -1
# 最小文字像素宽度
min_val_word = 5
# 分割后保存编号
number = 0
for start, end in rowinfo:
for j in range(width):
# 列中有字相关信息
if(not data[start: end, j].all()):
end_j = j
if(start_j < 0):
 start_j = j
 pass
# 列中无字信息
elif(data[start: end, j].all() and start_j >= 0):
if(end_j - start_j >= min_val_word):
img = data[start:end, start_j: end_j]
im2save = cv2.resize(img, (dsize, dsize)) #归一化处理
cv2.imwrite(root + '％d.jpg' ％ number, im2save)
number += 1
pass
start_j, end_j = -1, -1
