Introduction 📖

Deepfakes are synthetic media where a person in an existing image or video is replaced with someone else's likeness. They are created using artificial intelligence and can be difficult to distinguish from real media. This project provides a solution to detect such deepfake videos effectively.

Features ✨

• High Accuracy: Utilizes advanced neural networks to achieve high accuracy in detecting deepfakes.
• Pre-trained Models: Leverages pre-trained CNN models for efficient feature extraction.
• Temporal Modeling: Uses LSTM networks to analyze temporal aspects of videos.
• User-friendly Interface: Easy-to-use interface for uploading and analyzing videos.

Model Architecture 🧠

The Deepfake Detection System uses a combination of Convolutional Neural Networks (CNNs) and Long Short-Term Memory (LSTM) networks. Here’s an overview:

• CNNs: Used for extracting spatial features from individual frames.
• LSTM: Used for capturing temporal dependencies across frames.

Dataset 📚

The model is trained on a diverse dataset of real and fake videos. Some of the datasets used include:

• DFDC (Deepfake Detection Challenge) Dataset
• FaceForensics++

Results 📊

The Deepfake Detection System achieves high accuracy in detecting deepfakes. Here are some of the key metrics:

• Accuracy: 78%
• Precision: 77%
• Recall: 96%

Technical Details 🛠️

The Deepfake Detection System leverages the following technologies and frameworks:

• PyTorch: For building and training the deep learning models.
• OpenCV: For video processing and frame extraction.
• React: For creating the web-based frontend interface.
• Firebase: For database management and user authentication.
• Flask: For the backend API to interact with the model.

Key Components:

• Pre-processing: Video frames are extracted and resized to a uniform dimension.
• Feature Extraction: CNNs are used to extract meaningful features from each frame.
• Temporal Analysis: LSTM networks process the sequence of frames to detect temporal inconsistencies indicative of deepfakes.
• Post-processing: The results are aggregated and presented to the user with a confidence score.
