Food-or-Not-SigLIP2

Food-or-Not-SigLIP2 is a vision-language encoder model fine-tuned from google/siglip2-base-patch16-224 for binary image classification. It is trained to distinguish between images of food and non-food objects using the SiglipForImageClassification architecture.

Label Space: 2 Classes

The model classifies each image into one of the following categories:

Class 0: "food"
Class 1: "not-food"

Inference Code

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

# Load model and processor
model_name = "prithivMLmods/Food-or-Not-SigLIP2"  # Replace with your model path if different
model = SiglipForImageClassification.from_pretrained(model_name)

# Label mapping

Intended Use

Food-or-Not-SigLIP2 can be used for:

• Dietary Apps – Automatically classify images for food detection.
• Retail & E-commerce – Filter food vs non-food products visually.
• Content Moderation – Flag content containing food items.
• Dataset Curation – Separate food-related images for training or filtering.
