Practical overview

When it fits

Use it when working with 12306 CAPTCHA image recognition through a Python command line and you have the two required model data files.

Who it is for

  • Developers exploring machine-learning recognition of 12306 CAPTCHA images.
  • Users who need a command-line example for mapping image regions to recognized labels.

Documented uses

  • Run recognition on a CAPTCHA image and inspect the labels and grid positions returned.
  • Use the image-recognition script to get a predicted class and confidence value for an image.
  • Study a model-based CAPTCHA recognition approach with separate text and image model files.
Before you choose

Requirements & limits

The GitHub repository is public and specifies the Artistic-2.0 license.

  • The README requires both model.h5 and 12306.image.model.h5.
  • The documented main command is python3 main.py .
  • The project README directs people seeking 12306 CAPTCHA recognition to version 3.0.0 for its similar-image-search approach.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Recognize a 12306 CAPTCHA image

Use the project’s command-line recognizer to identify labels in a CAPTCHA image.

Before you start

  • Python 3, as indicated by the documented invocation.
  • The text-recognition data file model.h5 and image-recognition data file 12306.image.model.h5.
  • An input image such as img.jpg.

Steps

  1. Obtain the two required model data files from one of the download links listed in the project README.

  2. Place the model files where the project can access them.

  3. Run the command below, replacing `` with the input image path.

    Documented command
    python3 main.py

  4. Read the returned target labels and the label for each grid position.

Expected outcome

The example output lists the requested labels and recognized labels with grid coordinates.

Guide limitations

  • The README does not specify installation steps, model-file placement rules, or supported image formats beyond the example filename.
  • The documented example redirects standard error to /dev/null, but does not explain the messages suppressed.
