The ocr_detection model is compressed from [PP-OCRv3](https://github.com/PaddlePaddle/PaddleOCR/blob/release/2.6/doc/doc_en/PP-OCRv3_introduction_en.md) which released by [PaddleOCR](https://github.com/PaddlePaddle/PaddleOCR), which greatly improves the running speed on js at a small loss of accuracy.


# Usage

```js
import * as ocr from '@paddle-js-models/ocrdet';
// Load ocr_detect model
await ocr.load();
// Get text area points
const res = await ocr.detect(img);
```
