Quantifying Jump Height Using Markerless Motion Capture with a Single Smartphone
IEEE Open Journal of Engineering in Medicine and Biology, 2023 Goal: The countermovement jump (CMJ) is commonly used to measure lower-body explosive power. This study evaluates how accurately markerless motion capture (MMC) with a single smartphone can measure bilateral and unilateral CMJ jump height. Methods: First,

A Locality-based Neural Solver for Optical Motion Capture
SIGGRAPH Asia 2023 Conference Papers, 2023 We present a novel locality-based learning method for cleaning and solving optical motion capture data. Given noisy marker data, we propose a new heterogeneous graph neural network which treats markers and joints as different types of nodes, and uses graph convolution operations to extract the local features of markers and joints and transform them to ...

A Procedure for Automatically Estimating Model Parameters in Optical Motion Capture [PDF]
Procedings of the British Machine Vision Conference 2002, 2002 Abstract Model-based optical motion capture systems require knowledge of the position of the markers relative to the underlying skeleton, the lengths of the skeleton's limbs, and which limb each marker is attached to. These model parameters are typically assumed and entered into the system manually, although techniques exist for calculating some of ...

Validating Knee Varus Alignment Measurements Using Markerless Motion Capture
Geriatrics, 2023 This study aimed to determine the validity of specific knee varus alignment measurement methods. We measured the femorotibial angle (FTA) using radiography and optical motion capture and validated the FTA measurement using markerless motion capture.
