Detailed Description

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

this class implement 7 functions:

init(CParameterNetCDF) -> implements specific initialization of the branch intercorrelation which is launched within the factory.
exec(Cimage, Cfield, Cmesh) -> implements the block-matching, i.e loops over each mesh grid point, launch a specific block-matching method, launch a specific peak dectection method and finally fill the output field. The parallelization is realized using openMP and specific initialization are used for parallele fftw.
corners(Cimage, Cfield, Cmesh, Corner, i, j, k) -> implements the crop of images f and g acording to the mesh node location and the "element" size and provide coordonate of the sub_window corner.
correl(correlogram, F, G) -> is here virtual pur. It implements correlation sequence within derivated classes.
intercor(correlogram, F, G) -> it implements the convolution product between F and G and stores it in correlogram buffer.
FFt(correlogram, F, G) -> it implements the fast fourier transform of F and G in place.
iFFt(correlogram) -> it implements the inverse Fourier transform of the correlogram.

shift(correlogram) -> it shifts the correlogram to set image origin at the center of the picture.

Parameters

[in]	m_peak_type	: <int>. This is the kind of peak, i.e. interpP, max ...
[in]	this->m_storeMetrics	: <int>. 0 if metrics, i.e. correlograms and corrected image, musn't be save, otherwise they are stored.

The objective of this method is to perform the intercorrelation between 2 sub-images. This is done for every sub-images of size (m_zoi(0), m_zoi(1), m_zoi(2)) related to the mesh through oMesh.m_mask[element][Pixel indices]. As there is no depedency between each intercorrelation process a basic openMP parallelization is used

Peaks (peak type (e.g. interpP), number of peak to store (e.g. 1), number of space dimension (e.g. 2))

Implements Ccorrelation< T, Timg >.

template<typename T , typename Timg >

virtual void Ccorrelation_intercor< T, Timg >::init ( CParameterNetCDF & fp )

inlinevirtual

for an block matching correlation, required attributes are the peak approximation type, the storage mod for correlogram as well as previous init done in upper class, i.e. the median filter size.

Implements Ccorrelation< T, Timg >.

Reimplemented in Ccorrelation_intercor_fftw_phase< T, Timg >.
