Smoothing Data
Smoothing data can be necessary as part of your processing workflow. This tutorial discusses some options for smoothing your motion capture data before you export it to C3D format. Moving average and Butterworth filters are both valid options that could be employed, and we go over the differences between them.
Interpolation
Gaps in motion capture data can happen. Occlusions can be fixed as long as we understand what we are doing. In this tutorial, we talk about what a gap in data is, and ideal ways of fixing them, particularly using the principle of interpolation.
Processing your data in motion capture software
Is it better to process motion capture data directly in the software or wait to do it in Visual3D? In this video, we discuss which types of data processing you might want to do in Visual3D, and which could be done before the data is exported to C3D.
Cropping your data
A common practice in data processing is to remove unwanted data from the beginning and end of a motion capture trial, but is it a good idea? This video discusses the advantages and disadvantages of cropping your data and shows a practical example.
Mocap segment tracking
This video shows how to use marker clusters to track segments during dynamic motion capture trials. This can solve problems like skin movement artefact and camera occlusions so that the segment is tracked accurately.
