Swin Base Patch4 Window7 224 In22k

🚀 Swin Transformer (large-sized model)

The Swin Transformer is a pre - trained model on ImageNet - 21k, which can be used for image classification and other vision tasks.

🚀 Quick Start

The Swin Transformer model is pre - trained on ImageNet - 21k (14 million images, 21,841 classes) at a resolution of 224x224. It was introduced in the paper Swin Transformer: Hierarchical Vision Transformer using Shifted Windows by Liu et al. and first released in [this repository](https://github.com/microsoft/Swin - Transformer).

Disclaimer: The team releasing Swin Transformer did not write a model card for this model, so this model card has been written by the Hugging Face team.

✨ Features

• Hierarchical Feature Maps: The Swin Transformer builds hierarchical feature maps by merging image patches in deeper layers.
• Linear Computation Complexity: It has linear computation complexity to the input image size because self - attention is computed only within each local window.
• General - Purpose Backbone: It can serve as a general - purpose backbone for both image classification and dense recognition tasks.

📚 Documentation

Model description

The Swin Transformer is a type of Vision Transformer. It builds hierarchical feature maps by merging image patches (shown in gray) in deeper layers and has linear computation complexity to input image size due to computation of self - attention only within each local window (shown in red). It can thus serve as a general - purpose backbone for both image classification and dense recognition tasks. In contrast, previous vision Transformers produce feature maps of a single low resolution and have quadratic computation complexity to input image size due to computation of self - attention globally.

Intended uses & limitations

You can use the raw model for image classification. See the model hub to look for fine - tuned versions on a task that interests you.

💻 Usage Examples

Basic Usage

Here is how to use this model to classify an image of the COCO 2017 dataset into one of the 1,000 ImageNet classes:

from transformers import AutoImageProcessor, SwinForImageClassification
from PIL import Image
import requests

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

processor = AutoImageProcessor.from_pretrained("microsoft/swin-base-patch4-window7-224-in22k")
model = SwinForImageClassification.from_pretrained("microsoft/swin-base-patch4-window7-224-in22k")

inputs = processor(images=image, return_tensors="pt")
outputs = model(**inputs)
logits = outputs.logits
# model predicts one of the 1000 ImageNet classes
predicted_class_idx = logits.argmax(-1).item()
print("Predicted class:", model.config.id2label[predicted_class_idx])
