CAPTCHA-DS 🧩

CAPTCHA-DS is a collective intelligence project aimed at building a comprehensive CAPTCHA dataset. This project relies on a community-driven effort to label, verify, and organize CAPTCHA images for use in training and testing machine learning models.

Project Workflow 🚀

The dataset creation is organized into several steps, each with its own directory for processing and storing the images. Here's how you can contribute:

1. Working with Images (01.working) 📝

• All CAPTCHA images that need to be labeled are stored in the 01.working directory.
• Your task is to rename each image file based on the four-digit CAPTCHA text visible in the image.
• If the CAPTCHA text is 1234, rename the file to 1234.png.
• If a file with that name already exists, use the format:
  {captcha}.{number}.png
  For example, if 1234.png already exists, the next file would be 1234.1.png, then 1234.2.png, and so on.
• Once you have renamed an image, move it to the 02.labeled directory for further processing.

2. Labeling Completed (02.labeled) ✅

• This directory contains images that have been labeled and are awaiting verification.
• Once an image is in this directory, it will be reviewed for accuracy.

3. Verification (03.verified) 🔍

• Labeled images that have been verified are moved to the 03.verified directory.
• This is the final stage where the images are confirmed to be accurate and ready for dataset inclusion.

How to Contribute 🌟

1. Download Images: Start by accessing the images in the 01.working directory.
2. Rename Images: Follow the naming guidelines based on the CAPTCHA text you see.
3. Avoid Duplicates: If a file with the same CAPTCHA text already exists, use the {captcha}.{number}.png format.
4. Move Labeled Images: Transfer the renamed file to the 02.labeled directory once you're done.
5. Verification: You can also help verify the accuracy of labeled images in the 02.labeled directory and move them to 03.verified if correct.

Directory Structure 📂

CAPTCHA-DS/
├── 01.working/     # Images awaiting labeling
├── 02.labeled/     # Labeled images pending verification
└── 03.verified/    # Verified and final images

Conventions ✏️

• All CAPTCHA labels should be 4-digit numbers.
• Use the {captcha}.png format for file names.
• Use the {captcha}.{number}.png format if there's a name conflict.
