```
public VisualRecognition(java.lang.String versionDate)
```
    Instantiates a new `VisualRecognition`.
    
    Parameters:
    versionDate - The version date (yyyy-MM-dd) of the REST API to use. Specifying this value will keep your API calls from failing when the service introduces breaking changes.
  - VisualRecognition
```
public VisualRecognition(java.lang.String versionDate,
                 java.lang.String apiKey)
```
    Instantiates a new `VisualRecognition` with API Key.
    
    Parameters:
    versionDate - The version date (yyyy-MM-dd) of the REST API to use. Specifying this value will keep your API calls from failing when the service introduces breaking changes.
    apiKey - the API Key

  - setAuthentication
```
protected void setAuthentication(okhttp3.Request.Builder builder)
```
    Description copied from class: WatsonService
    
    Sets the authentication. Okhttp3 compliant.
    
    Overrides:
    
    setAuthentication in class WatsonService
    
    Parameters:
    builder - the new authentication
  - classify
```
public ServiceCall<ClassifiedImages> classify(ClassifyOptions classifyOptions)
```
    Classify images. Classify images with built-in or custom classifiers.
    
    Parameters:
    classifyOptions - the ClassifyOptions containing the options for the call
    
    Returns:
    a ServiceCall with a response type of ClassifiedImages
  - classify
```
public ServiceCall<ClassifiedImages> classify()
```
    Classify images. Classify images with built-in or custom classifiers.
    
    Returns:
    a ServiceCall with a response type of ClassifiedImages
  - detectFaces
```
public ServiceCall<DetectedFaces> detectFaces(DetectFacesOptions detectFacesOptions)
```
    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.
    
    Parameters:
    detectFacesOptions - the DetectFacesOptions containing the options for the call
    
    Returns:
    a ServiceCall with a response type of DetectedFaces
  - createClassifier
```
public ServiceCall<Classifier> createClassifier(CreateClassifierOptions createClassifierOptions)
```
    Create a classifier. Train a new multi-faceted classifier on the uploaded image data. Create your custom classifier with positive or negative examples. Include at least two sets of examples, either two positive example files or one positive and one negative file. You can upload a maximum of 256 MB per call. Encode all names in UTF-8 if they contain non-ASCII characters (.zip and image file names, and classifier and class names). The service assumes UTF-8 encoding if it encounters non-ASCII characters.
    
    Parameters:
    createClassifierOptions - the CreateClassifierOptions containing the options for the call
    
    Returns:
    a ServiceCall with a response type of Classifier
  - deleteClassifier
```
public ServiceCall<java.lang.Void> deleteClassifier(DeleteClassifierOptions deleteClassifierOptions)
```
    Delete a classifier.
    
    Parameters:
    deleteClassifierOptions - the DeleteClassifierOptions containing the options for the call
    
    Returns:
    a ServiceCall with a response type of Void
  - getClassifier
```
public ServiceCall<Classifier> getClassifier(GetClassifierOptions getClassifierOptions)
```
    Retrieve classifier details. Retrieve information about a custom classifier.
    
    Parameters:
    getClassifierOptions - the GetClassifierOptions containing the options for the call
    
    Returns:
    a ServiceCall with a response type of Classifier
  - listClassifiers
```
public ServiceCall<Classifiers> listClassifiers(ListClassifiersOptions listClassifiersOptions)
```
    Retrieve a list of classifiers.
    
    Parameters:
    listClassifiersOptions - the ListClassifiersOptions containing the options for the call
    
    Returns:
    a ServiceCall with a response type of Classifiers
  - listClassifiers
```
public ServiceCall<Classifiers> listClassifiers()
```
    Retrieve a list of classifiers.
    
    Returns:
    a ServiceCall with a response type of Classifiers
  - updateClassifier
```
public ServiceCall<Classifier> updateClassifier(UpdateClassifierOptions updateClassifierOptions)
```
    Update a classifier. Update a custom classifier by adding new positive or negative classes (examples) or by adding new images to existing classes. You must supply at least one set of positive or negative examples. For details, see [Updating custom classifiers] (https://console.bluemix.net/docs/services/visual-recognition/customizing.html#updating-custom-classifiers). Encode all names in UTF-8 if they contain non-ASCII characters (.zip and image file names, and classifier and class names). The service assumes UTF-8 encoding if it encounters non-ASCII characters. **Important:** You can't update a custom classifier with an API key for a Lite plan. To update a custom classifier on a Lite plan, create another service instance on a Standard plan and re-create your custom classifier. **Tip:** Don't make retraining calls on a classifier until the status is ready. When you submit retraining requests in parallel, the last request overwrites the previous requests. The retrained property shows the last time the classifier retraining finished.
    
    Parameters:
    updateClassifierOptions - the UpdateClassifierOptions containing the options for the call
    
    Returns:
    a ServiceCall with a response type of Classifier
  - getCoreMlModel
```
public ServiceCall<java.io.InputStream> getCoreMlModel(GetCoreMlModelOptions getCoreMlModelOptions)
```
    Retrieve a Core ML model of a classifier. Download a Core ML model file (.mlmodel) of a custom classifier that returns \"core_ml_enabled\": true in the classifier details.
    
    Parameters:
    getCoreMlModelOptions - the GetCoreMlModelOptions containing the options for the call
    
    Returns:
    a ServiceCall with a response type of InputStream
