Nsfw_Image_Detection_OSS

Nsfw_Image_Detection_OSS is an image classification vision-language encoder model fine-tuned from facebook/metaclip-2-worldwide-s16 for a binary NSFW detection task. It is designed to classify whether an image is Safe For Work (SFW) or Not Safe For Work (NSFW) using the MetaClip2ForImageClassification architecture.

Label Mapping

The model categorizes images into two classes:

• Class 0: SFW
• Class 1: NSFW

{
  "id2label": {
    "0": "SFW",
    "1": "NSFW"
  },
  "label2id": {
    "SFW": 0,
    "NSFW": 1
  }
}

Run with Transformers

!pip install -q transformers torch pillow gradio

import gradio as gr
import torch
from transformers import AutoImageProcessor, AutoModelForImageClassification
from PIL import Image

# Model name from Hugging Face Hub
model_name = "prithivMLmods/Nsfw_Image_Detection_OSS"

# Load processor and model
processor = AutoImageProcessor.from_pretrained(model_name)
model = AutoModelForImageClassification.from_pretrained(model_name)

# Define labels
LABELS = {
    0: "SFW",
    1: "NSFW"
}

    predictions = {LABELS[i]: round(probs[i], 3) for i in range(len(probs))}
    return predictions

Intended Use

The Nsfw_Image_Detection_OSS model is designed to classify images into SFW or NSFW categories.

Potential use cases include:

• Content Moderation: Automated filtering of unsafe or adult content.
• Social Media Platforms: Preventing the upload of explicit media.
• Enterprise Safety: Ensuring workplace-appropriate content in shared environments.
• Dataset Filtering: Cleaning large-scale image datasets before training.
• Parental Control Systems: Blocking inappropriate visual material.
