MRIaggr-calcContro_cpp: Compute contralateral normalization

In bozenne/MRIaggr: Management, Display, and Processing of Medical Imaging Data

Description

C++ function called by calcContralateral to seek the contralateral voxel and the contralateral values. For internal use.

Usage

calcContro_cpp(contrast, coords_px, index_k, index_k_contro, d_lim, 
         lambda, param_ref, var_ref, type_moy, type_med, type_NN, verbose)

Arguments

contrast	the contrast value of each voxel on a given slice. matrix.
coords_px	the coordinates of the observations. matrix.
index_k	the index of the observations on the hemisphere of interest. integer vector.
index_k_contro	the index of the observations on the contralateral hemisphere. integer vector.
d_lim	the distance within which the contralateral values are considered. numeric.
lambda	the importance of the penalization by the distance. numeric.
param_ref	the parameter to be used as a reference to identify the contralateral voxel. character.
var_ref	the variance of the reference parameter. numeric.
type_moy	should the mean contralateral value be used ? logical.
type_med	should the median contralateral value be used ? logical.
type_NN	should the closest contralateral voxel according to the reference parameter be used ? logical.
verbose	should the execution of the function be traced ? logical.
