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. For example:
<autnresponse> <action>LISTCLASSIFIERS</action> <response>SUCCESS</response> <responsedata> <classifier> <classifier>vehicles</classifier> <state>STALE</state> <numclasses>3</numclasses> <trainingoptions> <trainingoption> <key>iterations</key> <value>2000</value> </trainingoption> </trainingoptions> </classifier> </responsedata> </autnresponse>
The state
element specifies whether the classifier needs training. If this element contains the value "stale", train the classifier using the action BuildClassifier
. The other possible states are training
, trained
, and failed
.
The numclasses
element specifies the number of classes in the classifier.
If you set the trainingoptions
parameter to true
, the response also includes training options that you have set for the classifier.
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.
