Detailed Description

template<typename TSet>
struct DGtal::SetFromImage< TSet >

Aim: Define utilities to convert a digital set into an image.

Description of template class 'SetFromImage'

Template Parameters:

TImage

an model of CImageContainer concept.

Examples:

geometry/surfaces/greedy-plane-segmentation-ex2.cpp, geometry/surfaces/greedy-plane-segmentation.cpp, io/digitalSetFromVol.cpp, io/display3DToOFF.cpp, topology/3dBorderExtractionImg.cpp, topology/ctopo-2-3d.cpp, topology/ctopo-2.cpp, topology/volScanBoundary.cpp, topology/volToOFF.cpp, and topology/volTrackBoundary.cpp.

template<typename Set >

template<typename Image , typename ForegroundPredicate >

void DGtal::SetFromImage< Set >::append ( Set &  aSet, const ForegroundPredicate &  isForeground, typename Image::Domain::ConstIterator  itBegin, typename Image::Domain::ConstIterator  itEnd  )

inlinestatic

Append a Set to an existing image. Only points in the Set contained in the image domain are considered.

Precondition:

the ForegroundPredicate instance must have been created on the image aImage.

Parameters:

aSet	the set (maybe empty) to which points are added.
isForeground	instance of ForegroundPredicate to decide
itBegin	starting point in the input image Domain.
itEnd	ending point in the input image domain. which points to copy.

static void DGtal::SetFromImage< TSet >::append ( Set &  aSet, const Image &  aImage, const typename Image::Value  minVal, const typename Image::Value  maxVal, typename Image::Domain::ConstIterator  itBegin, typename Image::Domain::ConstIterator  itEnd  )

inlinestatic

Append an Image value set to an existing Set (maybe empty). This method will construct a default ForegroundPredicate instance as a simple thresholding (SimpleForegroundPredicate) of values in ]minVal,maxVal].

Parameters:

aSet	the set (maybe empty) to which points are added.
minVal	minimum value of the thresholding
maxVal	maximum value of the thresholding
itBegin	starting point in the input image Domain.
itEnd	ending point in the input image domain.

static void DGtal::SetFromImage< TSet >::append ( Set &  aSet, const Image &  aImage, const ForegroundPredicate &  isForeground  )

inlinestatic

Append a Set to an existing image. Only points in the Set contained in the image domain are considered.

Precondition:

the ForegroundPredicate instance must have been created on the image aImage.

Parameters:

aSet	the set (maybe empty) to which points are added.
aImage	image to convert to a Set.
isForeground	instance of ForegroundPredicate to decide which points to copy.
