Authentication
--------------

See the [Authentication](https://github.com/GoogleCloudPlatform/google-cloud-java#authentication) section in the base directory's README.

About Google Cloud Vision
----------------------------

Google [Cloud Vision API][cloud-vision] allows developers to easily integrate vision detection features within applications, including image labeling, face and landmark detection, optical character recognition (OCR), and tagging of explicit content.

See the [Vision client library docs][vision-client-lib-docs] to learn how to use this Cloud Vision API Client Library.

Getting Started
---------------
#### Prerequisites
You will need a [Google Developers Console](https://console.developers.google.com/) project with the Vision API enabled. [Follow these instructions](https://cloud.google.com/docs/authentication#preparation) to get your project set up. You will also need to set up the local development environment by [installing the Google Cloud SDK](https://cloud.google.com/sdk/) and running the following commands in command line: `gcloud auth login` and `gcloud config set project [YOUR PROJECT ID]`.

#### Installation and setup
You'll need to obtain the `google-cloud-vision` library.  See the [Quickstart](#quickstart) section to add `google-cloud-vision` as a dependency in your code.

#### Complete working example

In [AnnotateImage.java](../google-cloud-examples/src/main/java/com/google/cloud/examples/vision/snippets/AnnotateImage.java) we put a quick start example, which shows how you can use the Google Vision API to automatically annotate an image (like "cat", "whiskers", "mammal" for a picture of a cat).

For an example picture file, you can use the [wakeupcat.jpg](https://github.com/GoogleCloudPlatform/java-docs-samples/blob/master/vision/cloud-client/resources/wakeupcat.jpg) image from the samples repository.

Troubleshooting
---------------

To get help, follow the instructions in the [shared Troubleshooting document](https://github.com/GoogleCloudPlatform/gcloud-common/blob/master/troubleshooting/readme.md#troubleshooting).

Transport
---------
Vision uses gRPC for the transport layer.

Java Versions
-------------

Java 7 or above is required for using this client.

Versioning
----------

This library follows [Semantic Versioning](http://semver.org/).

It is currently in major version zero (``0.y.z``), which means that anything may change at any time and the public API should not be considered stable.
