In this innovative project, I designed and developed a comprehensive real-time hand gesture recognition system that utilizes advanced computer vision and machine learning techniques to recognize hand gestures in real time for various applications.
- PlatformWeb, Real-time Camera Feed
- StackPython, OpenCV, Mediapipe, Scikit-learn
- ModelRandom Forest Classifier
The system is built on a four-layered architecture:
1. Data Collection & Recognition Layer
2. Data Processing Layer
3. Model Training Layer
4. Real-Time Testing Layer
In the Data Collection & Recognition Layer, I integrated **Mediapipe** with a webcam to capture real-time images of hand gestures. The system uses:
- OpenCV (cv2):
For real-time video capture and image processing, enabling frame analysis for gesture recognition.
- Mediapipe:
For extracting hand landmarks from images, which are used to classify gestures.
- NumPy:
Used for handling arrays and numerical operations on feature vectors.
- Pickle:
For storing preprocessed data and trained models, ensuring efficient reuse.
The Data Processing Layer focuses on transforming captured images into usable data. This involves:
- Mediapipe Hand Landmark Extraction:
Extracts the 3D landmarks of the hand from the webcam feed, representing key points such as fingertips, palms, and knuckles.
- Data Preprocessing:
The landmarks are then converted into feature vectors using **NumPy** and saved in **Pickle** files for efficient model training.
The Model Training Layer is responsible for training the systems machine learning model using the preprocessed data. This layer includes:
- Random Forest Classifier:
The model is trained using a **Random Forest Classifier**, which classifies hand gestures based on the extracted features from the data.
- Scikit-learn:
This library is used for training and evaluating the model, ensuring optimal performance.
- Pickle:
The trained model is stored in a **Pickle** file for future use in real-time testing.
In the Real-Time Testing Layer, the system classifies hand gestures in real-time using the webcam feed. The testing layer involves:
- Webcam Feed:
Captures live video from the webcam, continuously processing each frame to detect and classify gestures.
- Real-Time Prediction:
The trained model classifies hand gestures on the fly, providing real-time feedback to users.
