Predator Object Tracking explanation: http://www.geek.com/articles/chips/predator-takes-visual-obj...

SandB0x2• 15 years ago

I'm not sure that counts as an explanation :) For details you could read his published papers on the subject:

http://info.ee.surrey.ac.uk/Personal/Z.Kalal/Publications/20...

That article adds little to nothing to the author's original explanation. I'd suggest you read this page instead: http://info.ee.surrey.ac.uk/Personal/Z.Kalal/tld.html

That page also has links to the papers referenced by SandB0x.

I thought he wasn't releasing this... why is Henrik Abelsson releasing this and not Zdeneki Kalai?

wladimir• 15 years ago

He already released it, and once you release something under GPL you can't take it back. You can stop hosting it, but someone else is free to develop further on it.

My bet is this won't do what the video was showing. I'd love to be contradicted.

SandB0x2• 15 years ago

Even so, I'm not sure this is a polite thing to do. I think it would be nice to respect the author's wishes for the moment:

We have received hundreds of emails asking for the source code ranging from practitioners, students, researchers up to top companies. The range of proposed projects is exciting and it shows that TLD is ready to push the current technology forward. This shows that we have created something "bigger" than originally expected and therefore we are going to postpone the release of our source code until announced otherwise. Thank you for understanding.

However as most of the tracking code is in Matlab - i.e. you can't just port this to your phone - I don't think the author has a great deal to lose here. If someone wants to re-implement the algorithms they may well need his expertise. (Edit: Looking at the code in more detail SammoJ may well be right, and this paragraph may be wrong.)

In fact, Henrik Abelsson may have more to lose if this is seen as poor etiquette, but I'm speculating here.

You will need at least the image processing toolbox and statistics toolbox for MATLAB to run the code.

sparky• 15 years ago

And at least version R2009B, to get the new syntax for unused function arguments or return values ("~"). Otherwise, search and replace them with dummy variable names to get it to run. Should just take a couple minutes.

IMHO, Zdenek Kalal has some short sighted view for business. Even if someone offered him a plane filled with money for his algorithm, or if he thought "hey, I can sell this shit! fuck the world! show me the money!", he fails at acknowledging that it doesn't really matter whether you created one of the best algorithms for image recognition: what matters is if you can do it again.

What I'm talking about is, what if instead of selling one of the golden eggs, you give that for free and create a reputation for yourself worldwide, so more people will be willing to hire the golden egg's goose?

Anyway.. Somewhere, Richard Stallman is smiling.. and I'm happy for that.

Also, I predict that after this source code leak, the link to the source code will be put back at his site.

alexsb92• 15 years ago

And you were right.

Some people make things just because they love to make things.

lwat• 15 years ago

Well he got a PhD for this one, that's something.

Let's not jump to conclusions...
