Grounding Dino Tiny

🚀 Grounding DINO model (tiny variant)

The Grounding DINO model extends a closed - set object detection model with a text encoder, enabling open - set object detection and achieving remarkable results in zero - shot scenarios.

🚀 Quick Start

The Grounding DINO model was proposed in Grounding DINO: Marrying DINO with Grounded Pre - Training for Open - Set Object Detection by Shilong Liu, Zhaoyang Zeng, Tianhe Ren, Feng Li, Hao Zhang, Jie Yang, Chunyuan Li, Jianwei Yang, Hang Su, Jun Zhu, Lei Zhang. It extends a closed - set object detection model with a text encoder, enabling open - set object detection. The model achieves remarkable results, such as 52.5 AP on COCO zero - shot.

✨ Features

You can use the raw model for zero - shot object detection (the task of detecting things in an image out - of - the - box without labeled data).

💻 Usage Examples

Basic Usage

import requests

import torch
from PIL import Image
from transformers import AutoProcessor, AutoModelForZeroShotObjectDetection 

model_id = "IDEA-Research/grounding-dino-tiny"
device = "cuda" if torch.cuda.is_available() else "cpu"

processor = AutoProcessor.from_pretrained(model_id)
model = AutoModelForZeroShotObjectDetection.from_pretrained(model_id).to(device)

image_url = "http://images.cocodataset.org/val2017/000000039769.jpg"
image = Image.open(requests.get(image_url, stream=True).raw)
# Check for cats and remote controls
# VERY important: text queries need to be lowercased + end with a dot
text = "a cat. a remote control."

inputs = processor(images=image, text=text, return_tensors="pt").to(device)
with torch.no_grad():
    outputs = model(**inputs)

results = processor.post_process_grounded_object_detection(
    outputs,
    inputs.input_ids,
    box_threshold=0.4,
    text_threshold=0.3,
    target_sizes=[image.size[::-1]]
)
