Hand Sign Classification using CNNs.Real-time prediction with webcam. Achieves high accuracy.

Hand Sign Classification using Deep Learning

Overview

In this project, two deep learning models were implemented and trained using TensorFlow. The first model was a simple manually implemented neural network, and two different optimizers were compared. The results were comparable with a significant difference.

The second model was a convolutional neural network (CNN) that significantly improved the classification performance. The difference between the performance of the simple network and the CNN was evident, showcasing the power of deep learning in hand sign recognition.

Real-time prediction using a webcam is also available in the repository.

Dataset

The dataset used in this project consists of images of hand signs representing numbers from 0 to 5. The dataset is stored in h5py files and contains both training and test sets. Each image is a 64x64 RGB image.

Prerequisites

To run this project, you will need the following dependencies:

• TensorFlow
• h5py
• numpy
• matplotlib
• OpenCV (cv2)

You can install these dependencies using the provided requirements.txt file:

pip install -r requirements.txt
