Automatic Gesture Spotting #33

Open OmarMAmin opened 8 years ago

OmarMAmin commented 8 years ago

Dear Nick,

I'm sorry for asking this question here but i tried to reach the http://www.nickgillian.com/forum/ forum but it's not working.

My question is about the following article http://www.nickgillian.com/wiki/pmwiki.php/GRT/AutomaticGestureSpotting

Does the GRT toolkit supports Gesture Spotting that it can detect the beginning and the end of the gesture automatically or as stated in the article it can differentiate between gestures and non gestures patterns?

Thank you and sorry for irrelevance

Hi OmarMAmin,

Yes, several of the GRT algorithms support automatic gesture spotting (although I'm continually trying to improve this across all algorithms).

You can enable/disable the automatic gesture spotting via the null rejection parameters in each classifier. Here null rejection refers to the null class or background class. Many of the GRT classifiers will automatically try and estimate parameters that enable the classifier to reject predictions that are too 'far' away from the trained model.

Null rejection is currently enabled for the following classifiers:

This wiki tutorial should hopefully explain things in more detail: http://www.nickgillian.com/wiki/pmwiki.php/GRT/AutomaticGestureSpotting
