Python2.7 +pytesser realizes the recognition method of simple captcha

An example of Python2.7+pytesser is presented in this paper. To share for your reference, specific as follows:

First, install es5EN2.7

PIL tools installed, then download the address is: http: / / www pythonware. com/products pil /, the use of pytesser need PIL library support.

Then download pytesser, download address is: http: / / code google. com p/pytesser/downloads/list

The ES30en.google.com website is not accessible. Click here to download.

Finally, install pytesser:

1. Unzip pytesser. Copy the unzip file to Lib\ ES41en-ES42en in the Python installation directory and use it directly. For example, my installation directory is C:\Python27\Lib\ ES46en-ES47en.

2. Add two directories to the environment variable.

C:\Python27\Lib\site-packages
C:\Python27\Lib\site-packages\pytesser-v0.0.1

3. Add the.pth file (pytesser-v0.0.0.pth) under C:\Python27\ site-ES61en, which contains only the string "pytesser-v0.0.1".

Once you have done this, you are ready to write the Python script for image text recognition. The reference script is as follows:

Open "Run" by cmd. Type "Python" to enter Python interactive mode. Enter the following code:

from pytesser import *
import ImageEnhance
image = Image.open('D:\\xiehao\\workspace\\python\\5.png')
# use ImageEnhance Can enhance the image recognition rate 
enhancer = ImageEnhance.Contrast(image)
image_enhancer = enhancer.enhance(4)
print image_to_string(image_enhancer)

TIP:

After verification, this method can be used in the case of the text in the picture is very clear; When the interference line is more pictures, it will not work. Plus my programming foundation is not good, the identification of the verification code, it is impossible to do. / (ㄒ o ㄒ) / ~ ~
