It was introduced in the paper [Depth Anything: Unleashing the Power of Large-Scale Unlabeled Data](https://arxiv.org/abs/2401.10891) by Lihe Yang et al. and first released in [this repository](https://github.com/LiheYoung/Depth-Anything). [Online demo](https://huggingface.co/spaces/LiheYoung/Depth-Anything) is also provided. Disclaimer: The team releasing Depth Anything did not write a model card for this model so this model card has been written by the Hugging Face team. ## Model description Depth Anything leverages the [DPT](https://huggingface.co/docs/transformers/model_doc/dpt) architecture with a [DINOv2](https://huggingface.co/docs/transformers/model_doc/dinov2) backbone. The model is trained on ~62 million images, obtaining state-of-the-art results for both relative and absolute depth estimation. <img src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/model_doc/depth_anything_overview.jpg" alt="drawing" width="600"/> <small> Depth Anything overview. Taken from the <a href="https://arxiv.org/abs/2401.10891">original paper</a>.</small> ## Intended uses & limitations You can use the raw model for tasks like zero-shot depth estimation. See the [model hub](https://huggingface.co/models?search=depth-anything) to look for other versions on a task that interests you. ### How to use Here is how to use this model to perform zero-shot depth estimation: ```python from transformers import pipeline from PIL import Image import requests # load pipe pipe = pipeline(task="depth-estimation", model="LiheYoung/depth-anything-small-hf") # load image url = 'http://images.cocodataset.org/val2017/000000039769.jpg' image = Image.open(requests.get(url, stream=True).raw) # inference depth = pipe(image)["depth"] ``` Alternatively, one can use the classes themselves: ```python from transformers import AutoImageProcessor, AutoModelForDepthEstimation 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("LiheYoung/depth-anything-small-hf") model = AutoModelForDepthEstimation.from_pretrained("LiheYoung/depth-anything-small-hf") # 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, ) ``` For more code examples, we refer to the [documentation](https://huggingface.co/transformers/main/model_doc/depth_anything.html#). ### BibTeX entry and citation info ```bibtex @misc{yang2024depth, title={Depth Anything: Unleashing the Power of Large-Scale Unlabeled Data}, author={Lihe Yang and Bingyi Kang and Zilong Huang and Xiaogang Xu and Jiashi Feng and Hengshuang Zhao}, year={2024}, eprint={2401.10891}, archivePrefix={arXiv}, primaryClass={cs.CV} } ```
