# Hair Segmentation (GPU)
This doc focuses on the
[below example graph](https://github.com/google/mediapipe/tree/master/mediapipe/graphs/hair_segmentation/hair_segmentation_android_gpu.pbtxt)
[example graph](https://github.com/google/mediapipe/tree/master/mediapipe/graphs/hair_segmentation/hair_segmentation_mobile_gpu.pbtxt)
that performs hair segmentation with TensorFlow Lite on GPU.

## Android
Please see [Hello World! in MediaPipe on Android](hello_world_android.md) for
general instructions to develop an Android application that uses MediaPipe.
The graph is used in the
[Hair Segmentation GPU](https://github.com/google/mediapipe/tree/master/mediapipe/examples/android/src/java/com/google/mediapipe/apps/hairsegmentationgpu)
example app. To build the app, run:
The graph below is used in the
[Hair Segmentation GPU Android example app](https://github.com/google/mediapipe/tree/master/mediapipe/examples/android/src/java/com/google/mediapipe/apps/hairsegmentationgpu).
To build the app, run:
```bash
bazel build -c opt --config=android_arm64 mediapipe/examples/android/src/java/com/google/mediapipe/apps/hairsegmentationgpu
```
To further install the app on android device, run:
