Constructor Detail

VisualRecognition

public VisualRecognition(String versionDate)

Instantiates a new Visual Recognition V3 service.

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(String versionDate,
                         String apiKey)

Instantiates a new Visual Recognition V3 service with a given 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

Method Detail

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<VisualClassification> classify(ClassifyImagesOptions options)

Classify.

Parameters:

options - the classify options

Returns:

the VisualClassification

createClassifier

public ServiceCall<VisualClassifier> createClassifier(ClassifierOptions options)

Train a new classifier on the uploaded image data. Upload a compressed (.zip) file of images (.jpg, .png, or .gif) with positive examples that show your classifier and another compressed file with negative examples that are similar to but do NOT show your classifier.

Parameters:

options - The parameters to create a classifier

Returns:

The created VisualClassifier

See Also:

ClassifierOptions, VisualClassifier

updateClassifier

public ServiceCall<VisualClassifier> updateClassifier(String classifierId,
                                                      ClassifierOptions options)

Update an existing classifier by adding new classes, or by adding new images to existing classes. To update the existing classifier, use several compressed (.zip) files, including files containing positive or negative images (.jpg, or .png). You must supply at least one compressed file, with additional positive or negative examples.

Parameters:

classifierId - the classifier id

options - The parameters to create a classifier

Returns:

The created VisualClassifier

See Also:

ClassifierOptions, VisualClassifier

deleteClassifier

public ServiceCall<Void> deleteClassifier(String classifierId)

Deletes a classifier.

Parameters:

classifierId - the classifier ID to delete

Returns:

the service call

See Also:

VisualClassifier

detectFaces

public ServiceCall<DetectedFaces> detectFaces(VisualRecognitionOptions options)

Detect faces.

Parameters:

options - the recognize text options

Returns:

the VisualClassification

getClassifier

public ServiceCall<VisualClassifier> getClassifier(String classifierId)

Retrieve information about a specific classifier. Only user-trained classifiers may be addressed.

Parameters:

classifierId - the classifier ID

Returns:

the classifier

See Also:

VisualClassifier

getClassifiers

public ServiceCall<List<VisualClassifier>> getClassifiers()

Retrieve the user-trained classifiers.

Returns:

the classifier list

See Also:

VisualClassifier

recognizeText

public ServiceCall<RecognizedText> recognizeText(VisualRecognitionOptions options)

Recognize text.

Parameters:

options - the recognize text options

Returns:

the RecognizedText

setUsernameAndPassword

@Deprecated
public void setUsernameAndPassword(String username,
                                               String password)

Deprecated.

The Visual Recognition V3 service use an api_key instead of username and password.
Use: WatsonService.setApiKey(String)

Overrides:

setUsernameAndPassword in class WatsonService

Parameters:

username - the username

password - the password
