Before using object detection, you must import a detector that is provided by HPE. The detectors provided by HPE are pre-trained, so you do not need to perform any training. For information about the detectors that are available, see Pre-Trained Object Detectors.
The following diagram shows how HPE Media Server stores information for object detection:
The "HPE Media Server database" represents the HPE Media Server datastore file or a database on an external database server. For information on setting up this database, see Introduction.
The HPE Media Server database can contain any number of detectors. An object detection task uses a single detector and finds instances of objects that are described by classes in that detector. For example, if you are processing video captured by a CCTV camera, you could use the roadscene
detector which contains classes for finding people, cars, and vans.
A detector contains a background class and a minimum of one foreground class. The background class contains images of uninteresting (background) objects and this class is never returned in a detection result. Only foreground classes are returned in detection results as they represent the categories of objects that you want to detect.
