Below are code samples on how to run MediaPipe on both mobile and desktop. We currently support MediaPipe APIs on mobile for Android only but will add support for Objective-C shortly.

Mobile

Hello World! on Android

Hello World! on Android should be the first mobile Android example users go through in detail. It teaches the following:

  • Introduction of a simple MediaPipe graph running on mobile GPUs for Sobel edge detection.
  • Building a simple baseline Android application that displays "Hello World!".
  • Adding camera preview support into the baseline application using the Android CameraX API.
  • Incorporating the Sobel edge detection graph to process the live camera preview and display the processed video in real-time.

Hello World! on iOS

Hello World! on iOS is the iOS version of Sobel edge detection example.

Object Detection with GPU

Object Detection with GPU illustrates how to use MediaPipe with a TFLite model for object detection in a GPU-accelerated pipeline.

Object Detection with CPU

Object Detection with CPU illustrates using the same TFLite model in a CPU-based pipeline. This example highlights how graphs can be easily adapted to run on CPU v.s. GPU.

Face Detection with GPU

Face Detection with GPU illustrates how to use MediaPipe with a TFLite model for face detection in a GPU-accelerated pipeline. The selfie face detection TFLite model is based on "BlazeFace: Sub-millisecond Neural Face Detection on Mobile GPUs", and model details are described in the model card.

Hand Detection with GPU

Hand Detection with GPU illustrates how to use MediaPipe with a TFLite model for hand detection in a GPU-accelerated pipeline.

Hand Tracking with GPU

Hand Tracking with GPU illustrates how to use MediaPipe with a TFLite model for hand tracking in a GPU-accelerated pipeline.

Hair Segmentation with GPU

Hair Segmentation on GPU illustrates how to use MediaPipe with a TFLite model for hair segmentation in a GPU-accelerated pipeline. The selfie hair segmentation TFLite model is based on "Real-time Hair segmentation and recoloring on Mobile GPUs", and model details are described in the model card.

Desktop

Hello World for C++

Hello World for C++ shows how to run a simple graph using the MediaPipe C++ APIs.

Preparing Data Sets with MediaSequence

Preparing Data Sets with MediaSequence shows how to use MediaPipe for media processing to prepare video data sets for training a TensorFlow model.

Object Detection on Desktop

Object Detection on Desktop shows how to run object detection models (TensorFlow and TFLite) using the MediaPipe C++ APIs.
