CNN_keras
A convolutional neural network for CAPTCHA recognition using Keras and PyTorch.
What is CNN_keras?
CNN_Keras is a convolutional neural network project built for CAPTCHA recognition. It uses deep learning to automatically identify and read text from CAPTCHA images, solving the problem of manual or script-based CAPTCHA solving. The project supports both Keras and PyTorch frameworks for flexibility.
Machine learning practitioners, researchers, and developers working on automation, computer vision, or CAPTCHA-solving tasks.
It offers a high-accuracy, open-source solution for CAPTCHA recognition with support for multiple deep learning frameworks, making it adaptable for different project needs.

Use Cases
Best For
- Training neural networks for CAPTCHA recognition tasks
- Researching image-based text recognition methods
- Automating CAPTCHA solving in testing environments
- Learning convolutional neural networks with practical examples
- Comparing Keras and PyTorch implementations for similar problems
- Building custom CAPTCHA solvers for specific image formats
Not Ideal For
- Applications needing immediate deployment without model training or dataset preparation
- CAPTCHAs with formats significantly different from those generated by CAPTCHA_generator
- Production systems requiring high-throughput, low-latency real-time recognition
- Teams lacking experience in deep learning frameworks or neural network training
Pros & Cons
Pros
Achieves 95% accuracy on single letters using a dataset of about 5000 samples, as stated in the README, making it reliable for targeted CAPTCHA recognition.
Offers both Keras and PyTorch implementations, with the PyTorch branch noted for 'more robust method,' providing adaptability for different project needs.
Specifically designed for recognizing CAPTCHA images from the linked CAPTCHA_generator, offering a straightforward solution for automation and testing tasks.
Includes example CAPTCHA images for reference and testing, as shown in the README, aiding in understanding and validation of the model.
Cons
Only works with CAPTCHAs generated by the specific CAPTCHA_generator, reducing its applicability to other CAPTCHA types without modification.
Users must generate or curate a dataset of CAPTCHA images for training, which can be time-consuming and resource-intensive.
The README highlights the PyTorch branch as having 'big changes' and being 'more robust,' implying the Keras version is less maintained or inferior.
The README is brief and lacks detailed instructions on setup, training, or deployment, which could hinder ease of use for less experienced developers.
