Example 2 with DetectedFaces

use of com.ibm.watson.developer_cloud.visual_recognition.v3.model.DetectedFaces in project java-sdk by watson-developer-cloud.

the class VisualRecognition method detectFaces.

/**
 * Detect faces in images.
 *
 * **Important:** On April 2, 2018, the identity information in the response to calls to the Face model was removed.
 * The identity information refers to the `name` of the person, `score`, and `type_hierarchy` knowledge graph. For
 * details about the enhanced Face model, see the [Release
 * notes](https://console.bluemix.net/docs/services/visual-recognition/release-notes.html#2april2018). Analyze and get
 * data about faces in images. Responses can include estimated age and gender. This feature uses a built-in model, so
 * no training is necessary. The Detect faces method does not support general biometric facial recognition. Supported
 * image formats include .gif, .jpg, .png, and .tif. The maximum image size is 10 MB. The minimum recommended pixel
 * density is 32X32 pixels per inch.
 *
 * @param detectFacesOptions the {@link DetectFacesOptions} containing the options for the call
 * @return a {@link ServiceCall} with a response type of {@link DetectedFaces}
