MediaPipe 网页端任务演示 许可说明 仓库：google-ai-edge/mediapipe-samples-web @ main bbb8974ffd450650ad5a1e7c1656c9debb8e38bf 原站：https://google-ai-edge.github.io/mediapipe-samples-web/ 这一件有两层许可，必须分开说： 【一】示例代码 仓库根目录 LICENSE 是 Apache License 2.0 全文（11,357 字节），覆盖本仓库的 TypeScript / HTML / CSS 源码与由它构建出来的 site/。全文见本文件末尾。 运行时用到的 @mediapipe/tasks-vision / tasks-audio / tasks-text（含 public/wasm 下的 wasm 运行时） 同样是 Apache-2.0（Google LLC 发布，见各包 package.json 的 "license": "Apache-2.0"）。 【二】模型权重（27 个，全部由 storage.googleapis.com/mediapipe-models/ 运行时下载） 仓库的 Apache-2.0 【不覆盖】这些权重，权重所在的 GCS 目录下也没有 LICENSE 文件 （实测 https://storage.googleapis.com/mediapipe-models/LICENSE、 .../object_detector/LICENSE、.../object_detector/efficientdet_lite0/float32/1/LICENSE 与 https://storage.googleapis.com/mediapipe-assets/LICENSE 全部 404，核对日期 2026-09-19）。 因此本站逐个权重查证了公开的许可声明，只镜像查得到声明的那 20 个，另外 7 个一个都没有下载。 许可证据有两种，都在下面逐条列出： (A) 任务文档页挂的 Model Card PDF，卡内写明 "LICENSED UNDER Apache License, Version 2.0"； (B) 权重文件自身的 TFLite Model Metadata（ModelMetadata.license 字段）， 值为 "Apache License, Version 2.0 http://www.apache.org/licenses/LICENSE-2.0"， 同一份元数据的 author 字段写 "MediaPipe"。用 flatbuffer 解析可复现。 已镜像的 20 个权重 -------------------------------------------------------------------------------- 1) blaze_face_short_range.tflite 证据 A https://storage.googleapis.com/mediapipe-assets/MediaPipe%20BlazeFace%20Model%20Card%20(Short%20Range).pdf 原话："LICENSED UNDER Apache License, Version 2.0" 2) blaze_face_full_range.tflite 证据 A https://storage.googleapis.com/mediapipe-assets/MediaPipe%20BlazeFace%20Model%20Card%20(Full%20Range).pdf 原话："LICENSED UNDER Apache License, Version 2.0" 3) face_landmarker.task 证据 A（模型包三份卡，全部 Apache-2.0） .../MediaPipe%20BlazeFace%20Model%20Card%20(Short%20Range).pdf .../Model%20Card%20MediaPipe%20Face%20Mesh%20V2.pdf .../Model%20Card%20Blendshape%20V2.pdf 原话："LICENSED UNDER Apache License, Version 2.0" 4) hand_landmarker.task 证据 A .../Model%20Card%20Hand%20Tracking%20(Lite_Full)%20with%20Fairness%20Oct%202021.pdf 原话："LICENSED UNDER ...
