ML Kit Vision Quickstart Sample App
Introduction
This ML Kit Quickstart app demonstrates how to use and integrate various vision based ML Kit features into your app.
Feature List
Features that are included in this Quickstart app:
- Object Detection - Detect, track, and classify objects in real time and static images
- Face Detection - Detect faces in real time and static images
- Text Recognition - Recognize text in real time and static images
- Barcode Scanning - Scan barcodes in real time and static images
- Image Labeling - Label images in real time and static images
- Custom Image Labeling - Birds - Label images of birds with a custom TensorFlow Lite model.
- Pose Detection - Detect the position of the human body in real time.
Getting Started
- Run the sample code on your Android device or emulator
- Try extending the code to add new features and functionality
How to use the app
This app supports three usage scenarios: Live Camera, Static Image, and CameraX enabled live camera.
Live Camera scenario
It uses the camera preview as input and contains these API workflows: Object detection & tracking, Face Detection, Text Recognition, Barcode Scanning, Image Labeling, and Pose Detection. There's also a settings page that allows you to configure several options:
- Camera
- Preview size - Specify the preview size of rear/front camera manually (Default size is chosen appropriately based on screen size)
- Enable live viewport - Toggle between blocking camera preview by API processing and result rendering or not
- Object detection / Custom Object Detection
- Enable multiple objects -- Enable multiple objects to be detected at once
- Enable classification -- Enable classification for each detected object
- Face Detection
- Landmark mode -- Toggle between showing no or all facial landmarks
- Contour mode -- Toggle between showing no or all contours
- Classification mode -- Toggle between showing no or all classifications (smiling, eyes open/closed)
- Performance mode -- Toggle between two operating modes (Fast or Accurate)
- Face tracking -- Enable or disable face tracking
- Minimum face size -- Choose the proportion of the head width to the image width
- Pose Detection
- Performance mode -- Allows you to switch between "Fast" and "Accurate" operation mode
- Show in-frame likelihood -- Displays InFrameLikelihood score for each landmark
Static Image scenario
The static image scenario is identical to the live camera scenario, but instead relies on images fed into the app through the gallery.
CameraX Live Preview scenario
The CameraX live preview scenario is very similar to the native live camera scenario, but instead relies on CameraX live preview. Note: CameraX is only supported on API level 21+.
