Python实现图片识别功能的示例分享

from pytesser import *

from PIL import Image, ImageEnhance

im = Image.open('D:\Python27\Lib\site-packages\pytesser\phototest.tif')

im2 = Image.open(r'D:\Python27\Lib\site-packages\pytesser\fnord.tif','r')

im3 = Image.open(r'F:\PROJECT\python\code\Study_1\src\20170424\cp.jpg','r') #文件读写模式以防报错

#图片处理1：：黑白处理

enhancer = ImageEnhance.Contrast(im3)

image2 = enhancer.enhance(5)

image2.show()

print image_to_string(image2)

#图片处理2: 降噪处理

imgry = im3.convert('L')  #灰度处理

#灰度处理基础上二值化处理

threshold = 140

table = []

for i in range(256):

  if i < threshold:

    table.append(0)

  else:

    table.append(1)

out = imgry.point(table, '1')

out.show()

text = image_to_string(out)

if text.isspace() :

  print "FAILE"

else:

  print text

#print text
