## Detailed Description

A single object detected on the scene on a particular video frame, defined as a bounding box.

## Member Function Documentation

## ◆ boundingBox()

Rect nx::sdk::analytics::IObjectMetadata::boundingBox | ( |  | ) | const
| inline

Returns
  Bounding box of an object detected in a video frame.

## ◆ getBoundingBox()

virtual void nx::sdk::analytics::IObjectMetadata::getBoundingBox | ( | Rect * | outValue | ) | const
| protected pure virtual

Called by boundingBox()

## ◆ getTrackId()

virtual void nx::sdk::analytics::IObjectMetadata::getTrackId | ( | Uuid * | outValue | ) | const
| protected pure virtual

Called by trackId()

## ◆ subtype()

virtual const char* nx::sdk::analytics::IObjectMetadata::subtype | ( |  | ) | const
| pure virtual

Returns
  Subclass of the object (e.g. vehicle type: truck, car, etc.).

## ◆ trackId()

Uuid nx::sdk::analytics::IObjectMetadata::trackId | ( |  | ) | const
| inline

Returns
  Id of the object track. Object track is a sequence of object detections from its first appearance on the scene till its disappearance. The same object can have multiple tracks (e.g. the same person entered and exited a room several times).
