Here you can download the three on-line boosting based trackers (Licensed under LGPL, use at own risk) as

In this version only Haar-like wavelets are used as basic features and weak classifiers are simple decision stumps. Further, no scale/ rotation adaption is implemented.

win32 binaries (preliminary version 0.3 - comments are more than welcome)

If the binaries do not run on your computer, you should install the Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package ATL Security Update.


Usage: Start the tracker using one of the following commands:

    BoostingTracker [myConfig.txt]
    SemiBoostingTracker [myConfig.txt]
    BeyondSemiBoostingTracker [myConfig.txt]

Mark the target object in the first frame using the mouse. Then change to the DOS-window and press <ENTER>. Tracking starts...

(a) start the program(b) initialize the object(c) tracking...

Additionally you might change some parameters manually using the config file:


% Boosting Tracking
version 0.3
Version of the Software
% source options: USB, AVI, JPEG
source = USB
% only if source is AVI OR JPEG
directory = ""
Specify the input video stream. One might use a USB webcamera connected to the computer, an AVI-video file or an JPEG image sequence. For the later two the filename or the folder containing the single images has to be specified.
% write debug information
debug = true
saveDir = "./results"
Tracking results can be saved during tracking. You can find the images with the tracked bounding box and a textfile with the coordinates of the tracked bounding box (format: #frameNumber upper left height width confidence)
% classifier (boosting)
numSelectors = 100 
Parameters for the on-line boosting classifier. The classifier will be more powerful if you increase the number of selectors (generally better tracking results, but slower).
% search region (size and resolution)
overlap = 0.99
searchFactor = 2
Parameters of the search region. The overlap (0<overlap<1) specifies the search grid, i.e., the number of evaluations (generally  more accurate tracking results with higher overlap, but slower). The search factor (searchFactor > 1) determines the size of the local search region with respect to the tracked object size. Note, for Semi-Supervised and Beyond Semi-Supervised Tracker the the values are automatically set once the object is lost (overlap = 0.98; search region is the whole image).
%initialization bounding box: MOUSE or COORDINATES
initBB = MOUSE

%if COORDINATES bb = x y width height
bb = 530 340 42 111
You can either select the bounding box of the object to be tracked manually (MOUSE) or by specifying the coordinates (COORDINATES).
