EraX-Anti-NSFW-V1.1

A Highly Efficient Model for NSFW Detection. Very effective for pre-publication image and video control, or for limiting children's access to harmful publications. You can either just predict the classes and their boundingboxes or even mask the predicted harmful object(s) or mask the entire image. Please see the deployment codes below.

Inference

To use the trained model, follow these steps:

Install the necessary packages:

pip install ultralytics supervision huggingface-hub

Download Pretrained model:

from huggingface_hub import snapshot_download
snapshot_download(repo_id="erax-ai/EraX-Anti-NSFW-V1.1", local_dir="./", force_download=True)

Simple Use Case:

from ultralytics import YOLO
from PIL import Image
import supervision as sv
import numpy as np

IOU_THRESHOLD        = 0.3
CONFIDENCE_THRESHOLD = 0.2

# pretrained_path = "erax-anti-nsfw-yolo11m-v1.1.pt"
# pretrained_path = "erax-anti-nsfw-yolo11s-v1.1.pt"
pretrained_path = "erax-anti-nsfw-yolo11n-v1.1.pt"

image_path_list = ["test_images/img_1.jpg", "test_images/img_2.jpg"]

model = YOLO(pretrained_path)
results = model(image_path_list,
                  conf=CONFIDENCE_THRESHOLD,
                  iou=IOU_THRESHOLD
                )


for result in results:
    annotated_image = result.orig_img.copy()
    h, w = annotated_image.shape[:2]
    anchor = h if h > w else w

    detections = sv.Detections.from_ultralytics(result)
    label_annotator = sv.LabelAnnotator(text_color=sv.Color.BLACK,
                                        text_position=sv.Position.CENTER,
                                        text_scale=anchor/1700)
    
    pixelate_annotator = sv.PixelateAnnotator(pixel_size=anchor/50)
    
    annotated_image = pixelate_annotator.annotate(
        scene=annotated_image.copy(),
        detections=detections
    )


    annotated_image = label_annotator.annotate(
        annotated_image,
        detections=detections
    )

    
    sv.plot_image(annotated_image, size=(10, 10))
