Kin2. A Kinect 2 toolbox for MATLAB

This paper introduces Kin2, a Kinect 2 toolbox for MATLAB. This toolbox encapsulates most of the Kinect for Windows SDK 2.0 functionality in a single class with high-level methods. The toolbox is written mostly in C++ with MATLAB Mex functions providing access to color, depth, infrared, and body index frames; coordinate mapping capabilities; real-time six-body tracking with 25 joints and hands states; face and high-definition face processing; and real-time 3D reconstruction. We showed that the performance of a Kin2 application decreases 30% on average with respect to a native C++ application, however, Kin reduces in one order of magnitude the average code length yielding a significant reduction in development time for prototyping and research.
