Is opencv tracking like:

http://docs.opencv.org/3.1.0/d2/d0a/t...

or http://docs.opencv.org/3.1.0/d5/d07/t...

based on TLD? In which case, am i allowed to use it (as i understoood TLD was copyrighted/patented) ?

I think so.

There are only a few modules which are not BSD. I can remember SIFT, but may be others...

Added info

Since OpenCV forces people to add stuff under BSD license, unless specifically stated otherwise in special licenses, the following rules apply

 // Copyright (C) 2013, OpenCV Foundation, all rights reserved.
 // Third party copyrights are property of their respective owners.

 // Redistribution and use in source and binary forms, with or without modification,

So basically you can do anything you want with it, as long as you keep the copyright notice!

Thanks both. So this is what's confusing me, how come TLD/predator and even the OpenTLD is GPL from George and are patented but yet here we have TLD in opencv..is that not a conflict ?

because from the moment someone rewrites the idea from scratch into a module, and does not just copy paste everything, it can be used :) Thats how I understand software licenses and patents. They rarely hold :)

Hey Steven, yeah that's true.

BTW - i tried the multitracker but i'm not sure i understand it. The code tells me the arguments are : * example: * example_tracking_multitracker Bolt/img/%04d.jpg * example_tracking_multitracker faceocc2.webm KCF

So for the first example, an image. How can it track anything based on a static image? The second example, a movie as the first argument and the tracking algorithm as the second.

I guess i don't understand how this is supposed to work. I'd like to modify it so i can use it for tracking objects from a webcam.
