Bone and prosthesis component models were registered to corresponding marker position data for effective three-dimensional animations.
Each marker position corresponds to a bin (i.e. a group of markers with the same genotype for all the plants studied, represented here by a single marker).
Relevant contributions dealing with intrinsic sources of systematic and random errors, such as the issues concerning camera calibration and filtering and smoothing of marker position data, are presented.
Anyway, the use of laser trackers obliges the operator to maintain the scanner head always visible, while the marker usage is quite critical because the measure precision depends strongly on the marker position.
This linkage group was generated by QTL IciMapping software considering the marker position and order retrieved from MAPMAKER ver. 2.0.
On the other hand, the performance of the algorithm decreases as the 2D marker position estimation error increases,.
For each one of the T, L and R markers, the difference in positioning with the average marker position was measured.
Remark 1.2 We call v D = D 1 ′ u x + D 2 ′ v x = D 1 u x + D 2 v x + D 3 w x. the drift velocity; it describes the marker position.
Once a marker position is assessed, its projection trace can be rebuilt by picking the most probable matching peak on each micrograph this is the closest peak to a micrograph projection point within a given distance.
Kinematic data, marker position data obtained by an optical motion capture system, were used for computation of the angles (varvec{q}), angular velocities (dot{varvec{q}}) and angular accelerations (ddot{varvec{q}}) of each joint.
The marker position data were low-pass filtered using a 2nd order Butterworth digital filter with one bidirectional pass (effectively making it a 4th order filter) and an effective cut-off frequency of 6 Hz.
