Description: The dataset was captured using the Microsoft Kinect V2 camera, and the Microsoft Kinect SDK 2.0.
Data was captured at 30 frames per second. We captured both the joint positions (X,Y,Z) and rotations (X,Y,Z,W) provided by the Kinect SDK for 20 joints, and recorded them in a text file format. More information about the text file format can be found in the Data Format section. After capture, we filtered the data using a Double Exponential Filter, using the method described here. To smooth the quaternion data, we filtered each component of the quaternion individually at each frame using the approach above. We then re-normalized the quaternion to have unit magnitude after the filtering process.
