## 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:** Semantic segmentation with `onnx-community/sapiens-seg-0.3b`.

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

const segmenter = await pipeline('image-segmentation', 'onnx-community/sapiens-seg-0.3b');

const url = 'https://huggingface.co/datasets/Xenova/transformers.js-docs/resolve/main/ryan-gosling.jpg';
const output = await segmenter(url);
console.log(output)
// [
//   {
//     score: null,
//     label: 'Background',
//     mask: RawImage { ... }
//   },
//   {
//     score: null,
//     label: 'Apparel',
//     mask: RawImage { ... }
//   },
//   ...
// ]
```

You can visualize the outputs with:
```js
for (const l of output) {
  l.mask.save(`${l.label}.png`);
}
```
