New features

  • Added bundled version of Face mesh detection API on Android. The public beta of the API works best for faces within ~2 meters (~7 feet) from camera and provides 468 3D points and triangle info for detected faces with low latency(14ms on Pixel 3 devices). When in BOUNDING_BOX_ONLY mode, the latency can be further reduced by ~20%.

Improvements

  • On Android, improved latency of Pose detection API by enabling fp16 model inference on supported CPUs.
  • On Android, improved Text recognition V2 by providing symbol and rotation information in recognition result.

August 23, 2022

Improvements

  • On Android, upgraded the unbundled version of the Barcode Scanning API. Improved recall, long tail latency, low-quality image tolerance and bounding box stability. Brought its performance on pair with that of the bundled version. Google Play Services handles this upgrade automatically, so no change is needed in your app.

New features

  • Added Text Recognition v2, which adds support for Chinese, Devanagari, Japanese and Korean scripts in addition to Latin and greatly increases range of supported languages. This API is offered as a bundled library and includes improved ML-based block/paragraph detection and updated models to boost recognition accuracy.
  • On Android, added unbundled version of Language Identification, backed by Google Play Services, to reduce the impact on apk size by about 500KB.

Improvements

Breaking changes

  • On Android, there are two breaking changes for Text Recognition:
    • The deprecated TextRecognition.getClient() method is removed. Please use TextRecognition.getClient(TextRecognizerOptions.DEFAULT_OPTIONS) instead.
    • TextRecognizerOptions is moved from com.google.mlkit.vision.text to com.google.mlkit.vision.text.latin.
  • On Android, for Barcode Scanning and Language Identification, the major version bumps are only due to breaking changes on non-public APIs. No code change is required when upgrading their dependency versions in your app.
  • On Android, ML Kit no longer supports API levels 16, 17 and 18, due to extremely low use. API level 19 (KitKat) is now the minimum level supported.

Note

  • On iOS, to keep your project on the v1 version of Text Recognition make sure to pin to version 2.2.0 or lower in your podfile. For example, adding pod 'GoogleMLKit/TextRecognition','2.2.0' to the pod file will pin your app to the latest v1 version of this feature.

New features

Improvements and bug fixes

  • The Pose Detection API recognizes more poses, such as when a user is directly facing the camera while doing squats and pushups.
  • The Pose Detection API base and accurate models are significantly smaller. This change does not impact the quality of the models.
  • The Android Vision APIs have been updated. The size of the unbundled variants in the pull-in SDKs backed by Google Play Services is reduced by approximately 16% (~160KB).

New features

  • ML Kit is no longer in Beta. All of ML Kit's APIs (excluding Pose Detection and Entity Extraction) have graduated to General Availability status.
  • Added the Entity Extraction API (Beta). This API allows you to detect and locate entities (e.g. addresses, date/time etc.) from raw text. It supports 11 entity types and 15 languages, using the same technology that powers smart text selection in Android Q+.

    Entity Extraction works fully offline (aside from a one-time download of selected language model, which is ~700KB), and supports both Android and IOS.

Improvements and bug fixes

  • Breaking change: The AutoML image labeling API is removed. Instead, custom image classification models trained using AutoML Vision Edge are now supported by the Custom Image Labeling and Custom Object Detection & Tracking APIs directly.
  • The Custom Image Labeling and Custom Object Detection & Tracking now support remote models that are hosted in Firebase.
    • Added RemoteModelSource, FirebaseModelSource, and CustomRemoteModel classes to support custom models hosted remotely on Firebase server. Also added the support for creating a LocalModel instance from a manifest path of a local custom model trained by AutoML Vision Edge.
    • For the custom image labeling API, added the remote custom model support to the CustomImageLabelerOptions class.
    • For the custom object detection API, added the remote custom model support to the CustomObjectDetectorOptions class.
  • On Android, significantly reduced the SDK size for Vision APIs. For APIs with unbundled variants (backed by Google Play Services) the pull-in SDK's size reduces by ~900KB (~65% of original size). For all other Vision APIs, the pull-in SDK's size reduces by ~600KB. The exception is Digital Ink Recognition, for which the SDK size remains the same.
  • On Android, enabled NNAPI acceleration for Object Detection & Tracking with Base models in STREAM_MODE on selected devices and OSes (Pixel 3, 3XL, 4, 4XL with Android Q or R at the moment), which provides faster model inference and saves energy.
  • On Android, fixed an issue in Barcode Scanning API where it did not work on some devices running with camera-camera2:1.0.0-beta08 version or later.

New features

  • On Android, added a “thin” variant of Image Labeling API, backed by Google Play Services. Reduces size impact to your app by ~3 MB compared to the bundled variant.

Improvements and bug fixes

  • Breaking change: Split Pose Detection into two libraries for size optimization. One library only bundles the fast models, while the other only bundles the accurate models. This helps save the application size, if you only use one set of the models. Same change happened to iOS: The PoseDetection pod now contains only the fast models. To use the accurate models, use the PoseDetectionAccurate pod instead.
  • On iOS, fixed a memory leak which occurred during pose detector deallocation.

New features

  • Added the Pose Detection API, a CPU-based, lightweight and versatile solution for developers to track a user’s physical actions in real time within their apps. Pose Detection offers a 33 point skeletal match (with hands and feet tracking) of a users body in real time and has been tuned to work well for complex athletic use cases.

    Pose detection also works fully offline, comes with two operating modes (fast and accurate), and supports both Android and iOS.

New features

  • Added a new Digital Ink Recognition API that recognizes text and shapes handwritten on a digital surface (e.g. touch screens). Supports 300+ languages, as well as emoji and autodraw. It is the same technology that powers handwriting recognition layouts in Gboard, the Google Translate apps and the Quick, Draw! game.

    Digital Ink Recognition works fully offline (aside from a one-time download of language packs), and supports both Android and iOS.

  • On Android, added support for specifying your own custom Executor for running expensive tasks like model loading and inference to Image Labeling and Object Detection and Tracking. With this release, all ML Kit APIs now support custom executors.

    By default, ML Kit uses a highly optimized, internally managed thread pool to run background tasks. This API can help with specialized use cases where developers want to keep full control over the threads in their app instead.

Improvements and bug fixes

  • On Android, for the Barcode Scanning API, fixed rotation handling of the input image.

  • On Android, added support for specifying your own custom Executor for running expensive tasks like model loading and inference to all APIs except Image Labeling and Object Detection and Tracking.

    By default, ML Kit uses a highly optimized, internally managed thread pool to run background tasks. This API can help with specialized use cases where developers want to keep full control over the threads in their app instead.

Improvements and bug fixes

  • Breaking change: On iOS, for the Barcode Scanning API, fixed a typo in BarcodePersonName and renamed its pronounciation property to pronunciation.
  • Fixed an issue on iOS in the Translate and Smart Reply APIs where the app would crash if the device locale does not specify a region (e.g. "en" instead of "en-US").

June 3, 2020

Android: 16.0.0 / iOS: 0.60.0

This is the first release of ML Kit as a standalone SDK, independent from Firebase. This SDK offers all the on-device APIs that were previously offered through the ML Kit for Firebase SDK. For more information on this change and instructions on migrating your existing apps, please follow our migration guide.

This release includes new features, improvements and bug fixes.

New features

Improvements and bug fixes

  • On Android, included support for Face Contours in “thin” variant of Face Detection API, backed by Google Play Services. Reduces size impact to your app by ~20.3 MB compared to bundled variant.
  • On Android, improved CameraX and Camera2 performance for Barcode Scanning and Face Detection APIs by moving image processing code from Java to native code.
  • Android Jetpack Lifecycle support has been added to all APIs. Developers can use addObserver to automatically manage the initiation and teardown of ML Kit APIs as the app goes through screen rotation or closure by the user / system. This makes CameraX integration easier.
  • Text Recognition API: the most prevalent recognized language is now provided
  • Face Detection API: the Euler X angle of a face is now provided.
  • Barcode Scanning API [bundled]: added support for broken PDF417 start/stop pattern detection, improving recall by 10%.
  • Object Detection and Tracking API: updated localizer model, improving average precision and reducing footprint by ~700KB.
