<div class="block">the GOTURN (Generic Object Tracking Using Regression Networks) tracker
|
|
|
|
GOTURN (CITE: GOTURN) is kind of trackers based on Convolutional Neural Networks (CNN). 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:

GOTURN architecture goturn.prototxt and trained model goturn.caffemodel are accessible on opencv_extra GitHub repository.</div>
