According to the described structure, a Pre-surgical Process (P) can be considered as a top level process composed by different sequential subprocesses: (SP1) Data Acquisition, (SP2) Image Post-Processing, (SP3) Trajectories study and (SP4) Surgery Area Estimation.
$$\end{document} Processing of movement trajectories For the analyses of the trajectories, the raw trajectories were first fit using a smoothing spline, computed to maintain a tolerance of 0.5 mm between the measured and smoothed values, and temporally resampled to have 21 points.
In practice, with advanced information processing technology, the trajectory can be precisely positioned on the map based on the data obtained from floating cars and GPS navigation.
Processing the marker trajectory file allows the calculation of relevant Lagrangian properties such as (i) the critical residence time in flammability areas for the ignition case and (ii) the marker Damköhler number for the autoignition case, both including the subgrid turbulence effects.
All trajectory processing was performed with MATLAB.
In the FCD processing, the vehicle trajectories are first map-matched to an OpenStreetMap road network graph of the region.
However, many previous studies have been somewhat limited in their scope due to the lack of workflows for collecting, processing, and analyzing trajectories in the field.
One called ProcessRheology.py, a configuration driven program performing all processing steps from particle trajectory inputs, thus presenting the various capabilities of the library (Figure 1).
Processing the obtained Lagrangian trajectory allowed determination of the mixing dynamics in the longitudinal, radial and circumferential directions, of the return length and return time distributions, and of the mean Eulerian flow fields.
A computer program plans the correct drilling trajectory by processing the lens-shaped hole projections of the interlocking holes from a single image.
