Re: Detection of open hand...need help

Hello, Erwin!
   
  I am doing the same thing that you. I have found some papers, that can be of 
help:
   
  Paul Viola and Michael J. Jones. Rapid Object Detection using
  a Boosted Cascade of Simple Features. IEEE CVPR, 2001.
   
  Freund, Y. & Schapire, R. E. (1996b). Experiments with a new
  boosting algorithm. In Machine Learning: Proceedings of the
  Thirteenth International Conference, Morgan Kauman, San
  Francisco, pp. 148-156, 1996
   
  An Extended Set of Haar-like Features for Rapid Object Detection
   
  I believe that the haar mehod is based in a search for a set of rectangular 
areas that best matches some predefined templates, but I dont know how to 
obtain this set - this is the training method. If you receive some links about 
references in this issue, please let me know. 
   
  Cheers,

  Hello everyone!

I am doing a project on hand gesture recognition. As a necessary 
first step, I want to detect an open hand (I use it as a "start" 
gesture), and then track it as it moves and changes its shape. 

I have read several messages regarding hand detection using haar-
features and haar-training. I have no knowledge of this method and I 
am in need of help. Could anyone, show me a tutorial or a link where 
I could learn this algorithm/method. How does the method work? Would 
it work if I wanted to detect an open hand even if the user is not 
wearing a long-sleeved shirt?

Several OpenCV members have had success in implementing this method. 
I was wondering if you could offer me some help in this topic.

I know I have a lot of questions, and I do not expect all of them to 
be answered. Any response, though would be greatly appreciated.

Thanks very much!

-Erwin
