Maskformer Swin Base Coco

🚀 MaskFormer

The MaskFormer model is trained on COCO panoptic segmentation (base - sized version, Swin backbone). It offers a unified approach to address instance, semantic, and panoptic segmentation.

🚀 Quick Start

The MaskFormer model trained here is for COCO panoptic segmentation. You can use it as follows:

from transformers import MaskFormerFeatureExtractor, MaskFormerForInstanceSegmentation
from PIL import Image
import requests

# load MaskFormer fine-tuned on COCO panoptic segmentation
feature_extractor = MaskFormerFeatureExtractor.from_pretrained("facebook/maskformer-swin-base-coco")
model = MaskFormerForInstanceSegmentation.from_pretrained("facebook/maskformer-swin-base-coco")

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

outputs = model(**inputs)
# model predicts class_queries_logits of shape `(batch_size, num_queries)`
# and masks_queries_logits of shape `(batch_size, num_queries, height, width)`
class_queries_logits = outputs.class_queries_logits
masks_queries_logits = outputs.masks_queries_logits

# you can pass them to feature_extractor for postprocessing
result = feature_extractor.post_process_panoptic_segmentation(outputs, target_sizes=[image.size[::-1]])[0]
# we refer to the demo notebooks for visualization (see "Resources" section in the MaskFormer docs)
predicted_panoptic_map = result["segmentation"]

✨ Features

• Unified Paradigm: MaskFormer addresses instance, semantic and panoptic segmentation with the same paradigm by predicting a set of masks and corresponding labels, treating all 3 tasks as instance segmentation.
• Trained on COCO: This model is trained on the COCO panoptic segmentation dataset, ensuring good performance on related tasks.

📚 Documentation

Model description

MaskFormer addresses instance, semantic and panoptic segmentation with the same paradigm: by predicting a set of masks and corresponding labels. Hence, all 3 tasks are treated as if they were instance segmentation.

Intended uses & limitations

You can use this particular checkpoint for semantic segmentation. See the model hub to look for other fine - tuned versions on a task that interests you.

How to use

As shown in the quick start section, you can use the model for semantic segmentation tasks.

Technical Information

• Model Type: MaskFormer model trained on COCO panoptic segmentation (base - sized version, Swin backbone).
• Training Data: COCO panoptic segmentation dataset.

Disclaimer

The team releasing MaskFormer did not write a model card for this model so this model card has been written by the Hugging Face team.
