Base Classes

SphericalWaveletObject<dimension of signal ,type of signal>::itkObject

Functions:
-get/setSubdivisionLevel() : sets the level of recursive, spherical icosahedron subdivision
-getTemplateMesh() [sphere] : returns the subdivided icosahdron mesh with lower levels preceding higher levels in the point list.
-get/setSignalVector (does not compute, only storage)
-get/setCoefficientVector (does not compute, only storage)
-IsSignalVectorAvailable() whether the signal information is available
-IsCoefficientVector() whether the coefficients are available
 :: -getIndicesSetAtResolution() //this the K set, used for the forward/backward filters
-getDifferenceIndicesSetAtResolution() //this is the M set, used for the forward/backward filters
Member Variables:
Private:
coeffs:itkVector<itkVector<double>> (k-th vector stores the coefficients for dimension k of signal) [Nxd], where N is the number of points in the template mesh, and d is the dimenstionality of the signal
signal:itkVector<itkVector<type of signal>> (k-th vector stores the signal at dimension k) [Nxd], where N is the number of points in the template mesh, and d is the dimenstionality of the signal
A,B,C,K,M …(what type of structure?)
itkMesh: TemplateMesh


SurfaceWaveletsObject<dim,type>::SphericalWaveletsObject<dim,type>

Functions:
-set/getSphericalParametrizedMesh() [internally we remesh]
-get/setSurfaceSignal

Filters

SphericalWaveletsSignalToCoefficientsFilter::processingObject

Functions:
-setInput(sphericalWaveletObject)
-getOutput(sphericalWaveletObject)


SphericalWaveletsCoefficentsToSignalFilter::processingObject

Functions:
-setInput(sphericalWaveletObject)
-getOutput(sphericalWaveletObject)


Example of use for shape analysis


SphericalWaveletObject swo<1,float>
swo.setSubdivision(5)
SphericalWaveletObject::surfaceSignalType s
swo.setSignal(s);
mesh = swo.getTemplateMesh(); //can visualize
SphericalWaveletSignalToCoefficientsFilter swf
swf.SetInput(swo);
swf.Update();
swg.GetOutput(swo);
