Hi! :) Is an OpenCV implementation of the TLD Real Time Tracker planned for a future release?

OpenTLD is an already written C++ implementation that could be easily integrated into OpenCV:

an OpenCV C++ version already exists although its not in the OpenCV library yet. Here is the link, its a ported version by George Nebehay,

Hi, In a demo of opencv Tracking algorithm, you can use several algorithms such as BOOSTING, TLD, MIL, MEDIANFLOW.
I tested it and found that BOOSTING algorithm is more robust to fast motion than other trackers. My dataset is sports dataset, so it contains many videos with fast motions. Other than that, STRUCK tracking is one of the best in current tracking benchmark The STRUCK implementation can be found on Github or my adapted and modified version

Ill definitly try that new algorithm. It's for openCV3.0 contrib tracking module right?

Hi Mubb, yes it is in OpenCV 3.0

Although I haven't used it, a TLD implementation is included in the upcoming 3.0.0 release, which is currently in beta.

Yes, but it's very slow :(

You can get it now by pulling in the contrib repository and building it. I just pulled in the tracking project and ahd it built. The TLD algorithm routinely crashed on me, and wasn't as good as all o the online videos show (don't know if it was overtuned, or the OpenCV implementation could use some polish).

I found the MILTrack algorithm in the contrib branch to be phenomenal though. Quite good.

I tested MIL, BOOSTING, MEDIANFLOW, TLD. None of them is good for sports datasets.
