Dpt Dinov2 Base Nyu

🚀 Model Card: DPT model with DINOv2 backbone

This model card introduces a DPT (Dense Prediction Transformer) model with a DINOv2 backbone. It demonstrates that using the DPT framework with DINOv2 as the backbone can create a powerful depth estimator.

✨ Features

• Utilizes the DPT framework with a DINOv2 backbone for depth estimation.
• Can be easily integrated with the Transformers library.

📦 Installation

Since the model uses the transformers library, you can install it using the following command:

pip install transformers torch pillow requests

💻 Usage Examples

Basic Usage

from transformers import AutoImageProcessor, DPTForDepthEstimation
import torch
import numpy as np
from PIL import Image
import requests

url = "http://images.cocodataset.org/val2017/000000039769.jpg"
image = Image.open(requests.get(url, stream=True).raw)

image_processor = AutoImageProcessor.from_pretrained("facebook/dpt-dinov2-base-nyu")
model = DPTForDepthEstimation.from_pretrained("facebook/dpt-dinov2-base-nyu")

# prepare image for the model
inputs = image_processor(images=image, return_tensors="pt")

with torch.no_grad():
    outputs = model(**inputs)
    predicted_depth = outputs.predicted_depth

# interpolate to original size
prediction = torch.nn.functional.interpolate(
    predicted_depth.unsqueeze(1),
    size=image.size[::-1],
    mode="bicubic",
    align_corners=False,
)

# visualize the prediction
output = prediction.squeeze().cpu().numpy()
formatted = (output * 255 / np.max(output)).astype("uint8")
depth = Image.fromarray(formatted)
