To list the classifiers that you have created, and check their status (whether they need training), use the following procedure.
To list classifiers
Run the action ListClassifiers:
http://localhost:14000/action=ListClassifiers&trainingoptions=TRUE
Media Server returns a list of classifiers that you have created.
To list the classes in a classifier
Run the action ListClasses:
http://localhost:14000/action=ListClasses&classifier=vehicles
&metadata=true
&imagelabels=true
Media Server returns a list of classes in the specified classifier.
If you set the action parameter imagelabels to true, Media Server returns the labels of images associated with each class.
If you set the action parameter metadata to true, Media Server returns the metadata you have added to each class.
