“…This is evidenced by the geometric analysis of the principal components, where the rigid-body translation and rotation components were much larger than the deformation components. As such, we believe that techniques focused on addressing marker cluster deformation [7,10,12,13,15,16] will have limited impact on resolving the STA problem. In a bone pin study on three Marino-mix sheep, Taylor et al [16] suggested that a large amount of STA is caused by rigid-body motions of the soft tissue, similarly to what was found in our study.…”

“…One group of bone motion estimators from skin markers rely purely on the measured marker trajectories and reconstruct the motion of the bones without assuming joints between the segments [6][7][8][9][10][11][12][13][14][15][16]. Another group relies on having an underlying model with joint constraints and reconstructs the motion of the model that best fits the observed skin marker trajectories [17][18][19][20][21].…”

“…Various surface marker optimisation methods have also been proposed to correct for STA through the application of marker clusters or solidification of marker groups (Andriacchi et al, 1998;Cheze et al, 1995;Lucchetti et al, 1998). The results of these techniques are encouraging, in particular the conventional singular value decomposition method along with additional redundant surface markers (Cereatti et al, 2006;Dumas and Cheze, 2009), with improvements of up to 33% accuracy based on the reduction of simulated STA.…”

“…Real-time ultrasound scan is restricted to the 2D study of upper layers (muscles) (Reeve and Dilley, 2009). Optoelectronic devices (Mac-Thiong et al, 2002) or three-dimensional (3D) digitizer (Black et al, 1996) limit the investigation to the external body shape, and have associated skin artefacts (Camomilla et al, 2009;Dumas and Cheze, 2009). Irradiating CT scanner and conventional magnetic resonance imaging (MRI) give access to 3D information but only in a small imaging space, limiting the acquisitions to the supine posture (Kim et al, 2007;Meakin et al, 2008).…”
