# ObjectTracker

This is a fork of the [C++ implementation of OpenTLD](https://github.com/gnebehay/OpenTLD) called TrackTLD.
OpenTLD was originally proposed in [1] and implemented by Georg Nebehay in C++.

This fork uses C++ implementations of correlation filter based trackers as short-term trackers. Both short-term trackers are modified variants of the visual trackers proposed in [2,3].
The short-term trackers are extended with target loss detection capabilities as in [4] and use the C++ implementation [5] of the FHOG features proposed in [6]. The detection cascade is only used to suggest possible target locations to the short-term trackers for redetection purposes. It cannot reinitialize the short-term trackers. The short-term trackers decide whether a suggested patch actually contains the target.

The system starts with the KCFcpp as default short-term tracker.

# Usage
If you have a webcam attached to your ROCK960, you can simply execute cftld in order to
try it out.

Press 'r' key, drag the mouse to draw the box to be tracked target. And press the Enter key to start tracking.

### Keyboard shortcuts
* `r` select a target
* `q` quit
* `l` toggle learning
* `a` toggle alternating mode (if true, detector is switched off when tracker is available)

### Documents
* [Installation instructions](installation.md)
* [Accuracy test instructions](accuracy_test_instruction.md)
* [Performance Report PDF](performance_report_objecttraker.pdf)

# Release History

### Version 0.1.3 - 2018-02-05 
* Add script to test accuracy.
* Add 2xA72 and 4xA53 performance data.

# Commercial Use (US)
The code using linear correlation filters may be affected by a US patent. If you want to use this code commercially in the US please refer to http://www.cs.colostate.edu/~vision/ocof_toolset_2012/index.php for possible patent claims.
