请问 ocr改为 web worker有demo可以参考吗？

测试了下使用OCR的2个模型，喂入类型为Imagebitmap数据或者OffscreenCanvas预测结果都是0. 应该是不兼容

const detModelPath = 'https://paddlejs.cdn.bcebos.com/models/fuse/ocr/ch_PP-OCRv2_det_fuse_activation/model.json';
const recModelPath = 'https://paddlejs.cdn.bcebos.com/models/fuse/ocr/ch_PP-OCRv2_rec_fuse_activation/model.json';

尝试了下用webworker demo里的方式对ocr库进行改造，detectRunner.predict(image); image是Imagebitmap类型 这里返回的结果全是0 .

不使用web worker的前提下，每进行一次识别，帧率都会下降很大，下降后会自动升上来但依然影响用户体验。我这边是直播流，我每5秒进行识别一次
