The main features are 2D detection, 2D tracking and 3D localization. Packages and features provided by below 3 projects with tag v0.3.0:

o object_analytics_node: ROS publisher and tests for object tracking in a ROS Image message, and for object localization 3D in a ROS PointCloud2 message from an RGB-D camera. OpenCV tracker is adopted for object tracking, with regular rectification from object detection results. Object segmentation over pointcloud2 image locates the detected objects in 3D camera coordination system.
