https://huggingface.co/facebook/maskformer-swin-small-ade with ONNX weights to be compatible with Transformers.js.

## Usage (Transformers.js)

If you haven't already, you can install the [Transformers.js](https://huggingface.co/docs/transformers.js) JavaScript library from [NPM](https://www.npmjs.com/package/@huggingface/transformers) using:
```bash
npm i @huggingface/transformers
```

**Example:** Scene segmentation with `onnx-community/maskformer-swin-small-ade`.

```js
import { pipeline } from '@huggingface/transformers';

// Create an image segmentation pipeline
const segmenter = await pipeline('image-segmentation', 'onnx-community/maskformer-swin-small-ade');

// Segment an image
const url = 'https://huggingface.co/datasets/hf-internal-testing/fixtures_ade20k/resolve/main/ADE_val_00000001.jpg';
const output = await segmenter(url);
console.log(output)
// [
//   {
//     score: 0.9240802526473999,
//     label: 'plant',
//     mask: RawImage { ... }
//   },
//   {
//     score: 0.967036783695221,
//     label: 'house',
//     mask: RawImage { ... }
//   },
//   ...
//   }
// ]
```

You can visualize the outputs with:
```js
for (let i = 0; i < output.length; ++i) {
  const { mask, label } = output[i];
  mask.save(`${label}-${i}.png`);
}
```

Note: Having a separate repo for ONNX weights is intended to be a temporary solution until WebML gains more traction. If you would like to make your models web-ready, we recommend converting to ONNX using [🤗 Optimum](https://huggingface.co/docs/optimum/index) and structuring your repo like this one (with ONNX weights located in a subfolder named `onnx`).
