The video vibration is annoying, because as we know it, this causes big barriers to programmers from recognising objects/people accurately. However, the thing is, when the vibrations are amplified, i mean hugely amplified with a set of algorithms, there are amazing results happenning, as demonsted in this picture.

This is the last post of the GSoC hand gesture detection series, and the trained HAAT classifier is finally released here.
This is only a short announcement, but the classifier in .xml file can be reached here in https://github.com/yandol/GstHanddetect.
The release contains two .xml classifier files, respectively they are for CLOSED PALM and FIST detection.
Hope this is useful.

A previous article has described a method to detect and recognise hand gestures using OpenCV, actually the c# wrapper of OpenCV called emgu CV. Details of this method can be found here a method of detecting and recognising hand gestures using Opencv. But Tongo’s project wrapped in emgu CV may not be easy to configure, so this article gives a new example transfering thet project to plain c++ OpenCV environment.

The first try of HAAR training was based on the tutorial mentioned in the previous post (see Collection of own hand gesture samples – the call for pictures, training method, tool and results). The aim was to go through all steps of HAAR training and see:
1) How positive and negative samples should be captured and setup for training?

Quite long time ago a call for hand gesture samples was made in here, unfortunately this call received few responses making contributions to the samples. Guess if I post free databases of hand gestures for high quality HAAR training then the situation would be quite different – kidding.

This post is the first of series articles discussing openCV HAAR classifier training and use, as it was implemented in GSoc 2012 project. Here in this post there is no complex algorithms presented, instead, this focuses on requirements and techniques for successful classifier training using openCV.
