Gesture Recognition Toolkit
The Gesture Recognition Toolkit (GRT) is a cross-platform, open-source, C++ machine learning library that has been specifically designed for real-time gesture recognition.
In addition to a comprehensive C++ API, the GRT now also includes an easy-to-use graphical user interface:
The GRT allows you to stream real-time data into the GUI from another application via Open Sound Control (OSC), record some training data, configure and train a gesture recognition system, stream the real-time prediction results out of the GUI to another application via OSC and save your trained model to a file so it can be loaded by the GRT C++ API.
Download: You can now download the GRT on GITHUB.
The GRT has been designed to:
- be easy to use and integrate into your existing C++ projects
- be compatible with any type of sensor or data input
- be easy to rapidly train with your own gestures
- be easy to extend and adapt with your own custom processing or feature extraction algorithms (if needed)
The GRT features a large number of algorithms that can be used to:
- recognize static postures (such as if a user has their hands in a specific posture or if a device fitted with an accelerometer is being held in a distinct orientation)
- recognize dynamic temporal gestures (such as a swipe or tap gesture)
- perform regression (i.e. continually map an input signal to an output signal, such as mapping the angle of a user's hands to the angle a steering wheel should be turned in a driving game)
Some example code demonstrating how to create a new gesture recognition pipeline, add a pre-processing modules, two feature-extraction modules, an ANBC classifier module, and a post-processing module, load some training and test data, and then train and test the pipeline.
The GRT currently works across several operating systems including:
- Windows (Tested on Windows XP, Windows 7)
- OS X (Tested on 10.7)
- Linux (Tested on Ubuntu 12)
GRT Machine Learning Algorithms
The current development build of the GRT contains machine-learning algorithms such as:
GRT Supporting Algorithms
In addition to the machine-learning algorithms, the GRT also contains a large number of pre-processing, post-processing, and feature-extraction algorithms such as:
GRT Wiki, Tutorials, Code Examples
The current development version of the GRT can be downloaded from github and also on the main GRT Wiki.
The GRT Wiki includes tutorials, code examples, and instuctions on how to download and integrate the GRT in your own C++ projects.
The wiki also features a guide to getting started if you've never used machine learning or gesture recognition before.
