Custom GroundingDINO Model

This is a custom trained GroundingDINO model for object detection and grounding, compatible with the Hugging Face Transformers library.

Model Details

• Model Type: GroundingDINO
• Number of Classes: 1180
• Training Dataset: Custom dataset with 1180 object classes
• Architecture: GroundingDINO with Swin-T backbone
• Transformers Compatible: ✅ Yes

Usage with Transformers

from transformers import AutoModel, AutoConfig, AutoTokenizer
import torch
from PIL import Image

# Load model and config
model = AutoModel.from_pretrained("your_username/your_model_name")
config = AutoConfig.from_pretrained("your_username/your_model_name")

# Load label map
import json
with open("label_map.json", "r") as f:
    label_map = json.load(f)

# Prepare text prompt
text_prompt = ". ".join(list(label_map.values())[:100]) + "."

# Load and preprocess image
image = Image.open("your_image.jpg").convert("RGB")
# Add your image preprocessing here

# Run inference
with torch.no_grad():
    outputs = model(images=image, text_prompts=[text_prompt])
    logits = outputs.logits
    boxes = outputs.boxes

Usage with Original Implementation

from model_loader import ModelLoader, quick_inference

# Quick inference
results = quick_inference('your_image.jpg')

# Or load model manually
model = ModelLoader.load_model(
    checkpoint_path='pytorch_model.bin',
    config_path='original_config.py',
    device='cuda'
)

label_map = ModelLoader.load_label_map('label_map.json')
