logo

”Hello, Let us help you easily recognize hand gestures 🖐️“


📝 Table of Contents

📙 Overview

  • Hand Gesture Recognition is a machine learning project that aims to recognize hand signs from 0 => 5
  • This project ranked 1st place among 21 teams with 81% accuracy, tested on unseen dataset.
  • Built using Python.
  • Using Libraries
    • opencv
    • numpy
    • matplotlib
    • pandas
    • scikit_image
    • scikit_learn
    • seaborn
    • joblib
  • You can view Data Set which was used to train the model
  • Project Report

🚀 How To Run

pip install -r requirements.txt
  • Add the needed data to test the model in the data folder next to the src folder
├───data
├───src
│   ├───main.py
│   └───predict.py
...
  • Navigate to the src directory
cd src
  • Run the main.py file
python main.py
File Description
Result Classification result of every image by order
Time Time taken for classifying the images
  • Features are saved in ./output.csv

🧱 Project Pipeline

  1. 📷 Read images
  2. 🔁 Preprocessing

🤖 Modules

Preprocessing Module

  1. Resize image for faster preprocessing
  2. Apply gamma correction to adjust lighting
  3. Convert image to YCbCr color space
  4. Apply segmentation on the skin color
  5. Skin masking
  6. Convert the segmented & original image to grayscale
  7. Erosion using a 5x5 elliptic kernel
  8. Dilation using a 17x17 elliptic kernel
  9. Region Filling using Contours
  10. Erosion again to clean the image from outside
  11. Masking the eroded image with the original one
  12. Crop image to fit the hand exactly
Input Output

Feature Extraction Module
