## Model Details: DPT-Hybrid
|
|
|
|
Dense Prediction Transformer (DPT) model trained on 1.4 million images for monocular depth estimation.
|
|
It was introduced in the paper [Vision Transformers for Dense Prediction](https://arxiv.org/abs/2103.13413) by Ranftl et al. (2021) and first released in [this repository](https://github.com/isl-org/DPT).
|
|
DPT uses the Vision Transformer (ViT) as backbone and adds a neck + head on top for monocular depth estimation.
|
|
|
|
|
|
This repository hosts the "hybrid" version of the model as stated in the paper. DPT-Hybrid diverges from DPT by using [ViT-hybrid](https://huggingface.co/google/vit-hybrid-base-bit-384) as a backbone and taking some activations from the backbone.
|
|
|
|
The model card has been written in combination by the Hugging Face team and Intel.

|
| Intended Use | Description |
|
|
| ----------- | ----------- |
|
|
| Primary intended uses | You can use the raw model for zero-shot monocular depth estimation. See the [model hub](https://huggingface.co/models?search=dpt) to look for fine-tuned versions on a task that interests you. |
|
|
| Primary intended users | Anyone doing monocular depth estimation |
|
|
| Out-of-scope uses | This model in most cases will need to be fine-tuned for your particular task. The model should not be used to intentionally create hostile or alienating environments for people.|

|
### How to use
|
|
|
|
Here is how to use this model for zero-shot depth estimation on an image:
|
|
|
|
```python
|
|
from PIL import Image
|
|
import numpy as np
|
|
import requests
|
|
import torch
|
|
|
|
from transformers import DPTForDepthEstimation, DPTFeatureExtractor
|
|
|
|
model = DPTForDepthEstimation.from_pretrained("Intel/dpt-hybrid-midas", low_cpu_mem_usage=True)
|
|
feature_extractor = DPTFeatureExtractor.from_pretrained("Intel/dpt-hybrid-midas")
|
|
|
|
url = "http://images.cocodataset.org/val2017/000000039769.jpg"
|
|
image = Image.open(requests.get(url, stream=True).raw)
|
|
|
|
# prepare image for the model
|
|
inputs = feature_extractor(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)
|
|
depth.show()
|
|
```
|

| ----------- | ----------- |
|
|
| Datasets | The dataset is called MIX 6, and contains around 1.4M images. The model was initialized with ImageNet-pretrained weights.|
|
|
| Motivation | To build a robust monocular depth prediction network |
|
|
| Preprocessing | "We resize the image such that the longer side is 384 pixels and train on random square crops of size 384. ... We perform random horizontal flips for data augmentation." See [Ranftl et al. (2021)](https://arxiv.org/abs/2103.13413) for more details. |

Table 1. Comparison to the state of the art on monocular depth estimation. We evaluate zero-shot cross-dataset transfer according to the
|
|
protocol defined in [30]. Relative performance is computed with respect to the original MiDaS model [30]. Lower is better for all metrics. ([Ranftl et al., 2021](https://arxiv.org/abs/2103.13413))
