This repository contains a Gradio-based web application that detects whether an image is a deepfake. The application uses a pre-trained InceptionResnetV1 model from the facenet_pytorch library for face recognition, and pytorch-grad-cam for visual explainability.

1. Face Detection: The application uses the MTCNN model to detect faces in the input image.
2. Face Classification: The detected face is then passed through an InceptionResnetV1 model to classify it as real or fake.
3. Explainability: The application uses Grad-CAM to generate a visual explanation of the model's decision.

The following libraries are required to run the application:

• torch
• torchvision
• facenet-pytorch
• numpy
• pillow
• opencv-python
• pytorch-grad-cam
• gradio

You can install these dependencies using the following command:

pip install -r requirements.txt

• app.py: The main application script.
• resnetinceptionv1_epoch_32.pth: The model checkpoint file. Download from here or Download Via Pinata through this hash QmUrarTy82uk2bUzty7Rhtc2XNCJHnsJy9UQhh7sMmAj78
• requirements.txt: List of dependencies.
• README.md: This file.

To run the application locally, execute the following command:

python app.py

This will launch the Gradio interface in your default web browser. You can then upload an image and get the prediction along with the explainability visualization.

• Upload an Image: Click on the "Upload" button and select an image file.
• Get Prediction: The app will process the image and display whether it is "real" or "fake" along with confidence scores.
• Explainability: The app will also display an image with visual explainability using Grad-CAM.

This project uses the following open-source libraries:

• Gradio
• PyTorch
• FaceNet-PyTorch
• PyTorch-Grad-CAM
