Inference with Hugging Face Pipeline

from transformers import pipeline

# Load the model
pipe = pipeline('image-classification', model="prithivMLmods/Deepfake-Detection-Exp-02-22", device=0)

# Predict on an image
result = pipe("path_to_image.jpg")
print(result)

Inference with PyTorch

from transformers import ViTForImageClassification, ViTImageProcessor
from PIL import Image
import torch

# Load the model and processor
model = ViTForImageClassification.from_pretrained("prithivMLmods/Deepfake-Detection-Exp-02-22")
processor = ViTImageProcessor.from_pretrained("prithivMLmods/Deepfake-Detection-Exp-02-22")

# Load and preprocess the image
image = Image.open("path_to_image.jpg").convert("RGB")
inputs = processor(images=image, return_tensors="pt")

# Perform inference
with torch.no_grad():
    outputs = model(**inputs)
    logits = outputs.logits
    predicted_class = torch.argmax(logits, dim=1).item()

# Map class index to label
label = model.config.id2label[predicted_class]
print(f"Predicted Label: {label}")

Limitations

1. Generalization Issues – The model may not perform well on deepfake images generated by unseen or novel deepfake techniques.
2. Dataset Bias – The training data might not cover all variations of real and fake images, leading to biased predictions.
3. Resolution Constraints – Since the model is based on vit-base-patch32-224-in21k, it is optimized for 224x224 image resolution, which may limit its effectiveness on high-resolution images.
4. Adversarial Vulnerabilities – The model may be susceptible to adversarial attacks designed to fool vision transformers.
5. False Positives & False Negatives – The model may occasionally misclassify real images as deepfake and vice versa, requiring human validation in critical applications.

Intended Use

1. Deepfake Detection – Designed for identifying deepfake images in media, social platforms, and forensic analysis.
2. Research & Development – Useful for researchers studying deepfake detection and improving ViT-based classification models.
3. Content Moderation – Can be integrated into platforms to detect and flag manipulated images.
4. Security & Forensics – Assists in cybersecurity applications where verifying the authenticity of images is crucial.
5. Educational Purposes – Can be used in training AI practitioners and students in the field of computer vision and deepfake detection.
