Syntax

public class TrackerGOTURN : Tracker, ICvPtrHolder

Remarks

• While taking all advantages of CNN trackers, GOTURN is much faster due to offline training without online fine-tuning nature.

• GOTURN tracker addresses the problem of single target tracking: given a bounding box label of an object in the first frame of the video,

• we track that object through the rest of the video.NOTE: Current method of GOTURN does not handle occlusions; however, it is fairly

• robust to viewpoint changes, lighting changes, and deformations.

• Inputs of GOTURN are two RGB patches representing Target and Search patches resized to 227x227.

• Outputs of GOTURN are predicted bounding box coordinates, relative to Search patch coordinate system, in format X1, Y1, X2, Y2.

• Original paper is here: [http://davheld.github.io/GOTURN/GOTURN.pdf]

• As long as original authors implementation: [https://github.com/davheld/GOTURN#train-the-tracker]

• Implementation of training algorithm is placed in separately here due to 3d-party dependencies:

• [https://github.com/Auron-X/GOTURN_Training_Toolkit]

• GOTURN architecture goturn.prototxt and trained model goturn.caffemodel are accessible on opencv_extra GitHub repository.
