Image Labeling
plat_iosplat_android
With ML Kit's image labeling APIs, you can recognize entities in an
image without having to provide any additional contextual metadata, using either
an on-device API or a cloud-based API.
Image labeling gives you insight into the content of images. When you use the
API, you get a list of the entities that were recognized: people, things,
places, activities, and so on. Each label found comes with a score that
indicates the confidence the ML model has in its relevance. With this
information, you can perform tasks such as automatic metadata generation
and content moderation.
If you're a Flutter developer, you might be interested in
FlutterFire,
which includes a plugin for Firebase's ML Vision APIs.

Google Knowledge Graph entity IDs
In addition the text description of each label that ML Kit returns, it also
returns the label's Google Knowledge Graph entity ID. This ID is a string that
uniquely identifies the entity represented by the label, and is the same ID used
by the Knowledge Graph Search API.
You can use this string to identify an entity across languages, and
independently of the formatting of the text description.
