Detailed Description

template<typename T, typename Timg>
class Cfield_opticalFlow_integrated< T, Timg >

In this class, specific projection field method is implemented. In the case of O.F.F.E.M. the node value must be identified through a projection, so "fromField2Mod" implements a parallelized loop over image pixel and identifies modes from a least square method strategy.

Parameters
[in]m_ref: std::vector<int>[3]. It defines the reference location of shape functions.

transfert fields, coming from a previous image or from a previous method, to modes vector. In the case of OFI, the transfert requires a projection on modes

T[i] is solution of the following system:

$ \left(\sum_{dim = 0}^{dim = n}{K_{dim}\left[i,j\right]}\right).T[i] = \sum_{dim = 0}^{dim = n}{F_{dim}}\left[j\right]$

with :

$ K_{dim}\left[i,j\right] = \sum_{x=0;y=0}^{x=width;y=height}N_{xy}[dim][i].N_{xy}[dim][j]$

$ F_{dim}\left[j\right] = \sum_{x=0;y=0}^{x=width;y=height}U_{xy}[dim].N_{xy}[dim][j]$

i and j the range from 0 to mod number

shape functions are required the knowledge of the reference location. In some cases this origin could be automatically set to the image center thus this is a user parameter which must be captured here

require improvement, pb with netcdf load std::vector<T>. When a int vector is declared within parameter file only the first value is captured, thus x, y and z reference position are here separated

use the current or the previous "oMesh.num_var()" musn't be problematic since dimensions (i.e. 2D or 3D) remains constant for a set of picture. However the number of modes could change.//

one assumes that if successive OFI methods are used the set of required modes is identical. It allows a faster mode transfert//
