Maskformer Swin Large Ade

🚀 MaskFormer

The MaskFormer model is trained on ADE20k for semantic segmentation (large-sized version with Swin backbone). It offers a unified approach to address instance, semantic, and panoptic segmentation.

🚀 Quick Start

The MaskFormer model was introduced in the paper Per-Pixel Classification is Not All You Need for Semantic Segmentation and first released in this repository.

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.

✨ Features

• Unified Paradigm: MaskFormer addresses instance, semantic, and panoptic segmentation using the same approach, by predicting a set of masks and corresponding labels.
• Visual Representation: A clear architecture image is provided to help understand the model's structure.

📚 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.

💻 Usage Examples

Basic Usage

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

url = "https://huggingface.co/datasets/hf-internal-testing/fixtures_ade20k/resolve/main/ADE_val_00000001.jpg"
image = Image.open(requests.get(url, stream=True).raw)

processor = MaskFormerImageProcessor.from_pretrained("facebook/maskformer-swin-large-ade")
inputs = processor(images=image, return_tensors="pt")

model = MaskFormerForInstanceSegmentation.from_pretrained("facebook/maskformer-swin-large-ade")
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 processor for postprocessing
# we refer to the demo notebooks for visualization (see "Resources" section in the MaskFormer docs)
predicted_semantic_map = processor.post_process_semantic_segmentation(outputs, target_sizes=[image.size[::-1]])[0]
