Dense Prediction Transformer DPT (large-sized model) fine-tuned on ADE20k
Dense Prediction Transformer (DPT) model trained on ADE20k for semantic segmentation. It was introduced in the paper Vision Transformers for Dense Prediction by Ranftl et al. and first released in this repository.
It is suited for image segmentation, specifically, semantic segmentation - tasks such as is seen the output below:
Disclaimer: The team releasing DPT did not write a model card for this model so this model card has been written by the Hugging Face in conjunction with Intel team.
Model description
DPT uses the Vision Transformer (ViT) as backbone and adds a neck + head on top for semantic segmentation. It is based on MiDaS v3.0 as described in the paper above.
Intended uses & limitations
You can use the raw model for semantic segmentation. See the model hub to look for fine-tuned versions on a task that interests you.
Results:
According to the authors, at the time of publication, when applied to semantic segmentation, dense vision transformers set a new state of the art on ADE20K with 49.02% mIoU.
We further show that the architecture can be fine-tuned on smaller datasets such as NYUv2, KITTI, and Pascal Context where it also sets the new state of the art. Our models are available at
How to use - Demonstration of Image Semantic Segmentation using DPTs
Here is how to use this model:
from transformers import DPTFeatureExtractor, DPTForSemanticSegmentation
from PIL import Image
import requests
url = "http://images.cocodataset.org/val2017/000000026204.jpg"
image = Image.open(requests.get(url, stream=True).raw)
feature_extractor = DPTImageProcessor .from_pretrained("Intel/dpt-large-ade")
model = DPTForSemanticSegmentation.from_pretrained("Intel/dpt-large-ade")
inputs = feature_extractor(images=image, return_tensors="pt")
outputs = model(**inputs)
logits = outputs.logits
print(logits.shape)
logits
prediction = torch.nn.functional.interpolate(
logits,
size=image.size[::-1], # Reverse the size of the original image (width, height)
mode="bicubic",
align_corners=False
)
# Convert logits to class predictions
prediction = torch.argmax(prediction, dim=1) + 1
# Squeeze the prediction tensor to remove dimensions
prediction = prediction.squeeze()
# Move the prediction tensor to the CPU and convert it to a numpy array
prediction = prediction.cpu().numpy()
# Convert the prediction array to an image
predicted_seg = Image.fromarray(prediction.squeeze().astype('uint8'))
# Define the ADE20K palette
