# NullObjectClassImageData

Removes (deletes) all images and annotations from a recognizer, but does not remove the training generated from the images. This means that you can run analysis but the training images are no longer stored in the database.

Removing the training images means that the training cannot be updated in future. For example, if you want to add new training images or a new class to your recognizer, you will need to supply all of the images and annotations for each class again. If future versions of Media Server feature enhancements to object class recognition that require retraining, you will need to supply all of the images and annotations again.

Type: synchronous
