# Building an ASL Recognition System: A Complete Guide
American Sign Language (ASL) recognition is a fascinating application of computer vision and deep learning. In this comprehensive guide, I'll walk you through the entire process of building a CNN-based gesture recognition system that achieves 92.6% accuracy.
## Project Overview
This project was developed as part of my final-year research, focusing on real-time ASL alphabet recognition using convolutional neural networks.
### Key Achievements
- **92.6% accuracy** on test dataset
- **0.90 F1 score** across all classes
- Trained on **13,000 images** across **26 ASL hand gesture classes**
## Dataset Preparation
The first step in any ML project is data preparation...
