+# Google Cloud Vision API Java examples
+
+This directory contains [Cloud Vision API](https://cloud.google.com/vision/) Java samples.
+
+## Prerequisites
+
+### Download Maven
+
+This sample uses the [Apache Maven][maven] build system. Before getting started, be
+sure to [download][maven-download] and [install][maven-install] it. When you use
+Maven as described here, it will automatically download the needed client
+libraries.
+
+[maven]: https://maven.apache.org
+[maven-download]: https://maven.apache.org/download.cgi
+[maven-install]: https://maven.apache.org/install.html
+
+### Setup
+
+* Create a project with the [Google Cloud Console][cloud-console], and enable
+  the [Vision API][vision-api].
+* Set up your environment with [Application Default Credentials][adc]. For
+    example, from the Cloud Console, you might create a service account,
+    download its json credentials file, then set the appropriate environment
+    variable:
+
+    ```bash
+    export GOOGLE_APPLICATION_CREDENTIALS=/path/to/your-project-credentials.json
+    ```
+
+[cloud-console]: https://console.cloud.google.com
+[vision-api]: https://console.cloud.google.com/apis/api/vision.googleapis.com/overview?project=_
+[adc]: https://cloud.google.com/docs/authentication#developer_workflow
+
+## Samples
+
+### Label Detection
+
+This sample annotates an image with labels based on its content.
+
+- [Java Code](label)
+
+### Face Detection
+
+This sample identifies faces within an image.
+
+- [Quickstart Walkthrough](https://cloud.google.com/vision/docs/face-tutorial)
+- [Java Code](face_detection)
+
+### Landmark Detection Using Google Cloud Storage
+
+This sample identifies a landmark within an image stored on
+Google Cloud Storage.
+
+- [Documentation and Java Code](landmark_detection)
+
+### Text Detection Using the Vision API
+
+This sample uses `TEXT_DETECTION` Vision API requests to build an inverted index
+from the stemmed words found in the images, and stores that index in a
+[Redis](redis.io) database.  The example uses the
+[OpenNLP](https://opennlp.apache.org/) library (Open Natural Language
+Processing) for finding stopwords and doing stemming. The resulting index can be
+queried to find images that match a given set of words, and to list text that
+was found in each matching image.
+
+[Documentation and Java Code](text)

+
+## Run the sample
+
+To build and run the sample, run the following from this directory:
+
+```bash
+mvn clean compile assembly:single
+java -cp target/vision-face-detection-1.0-SNAPSHOT-jar-with-dependencies.jar com.google.cloud.vision.samples.facedetect.FaceDetectApp data/face.jpg output.jpg
+```
+
+For more information about face detection see the [Quickstart][quickstart]
+guide.
