A PyTorch-based end-to-end CNN model for recognizing captchas (digits and letters) without manual image preprocessing, using self-generated training data via ImageCaptcha. It serves primarily as an educational project demonstrating deep learning OCR workflows.

Use cases

• recognize captcha images with deep learning
• train a CNN to read digits and letters from images
• learn end-to-end OCR with pytorch
• generate labeled captcha training data
• build a multi-label character classification model

When to choose

• you want to learn CNN-based OCR with PyTorch
• you need to recognize simple generated captchas of digits and letters
• you want a complete train/test/predict pipeline example

When to avoid

• you need production-grade OCR for complex or noisy captchas
• you require actively maintained software with recent updates
• you need support for arbitrary text, distorted, or adversarial captchas
