I don't think so, but it might be interesting, what do you need it for?
Usually, you filter the Riesz components, for example with a StructureTensor: https://github.com/InsightSoftwareConsortium/ITKIsotropicWavelets/blob/master/test/itkStructureTensorWithGeneralizedRieszTest.cxx
Or use them to get a steerable RieszRotationMatrix: https://github.com/InsightSoftwareConsortium/ITKIsotropicWavelets/blob/master/test/itkRieszRotationMatrixTest.cxx
Thanks for replying. I wonder if it can transform rotated Riesz coefficients back into a signal? And it seems that the StructureTensor does the filtering and inverse transforming at the same time. Maybe there is a code to transform Riesz coefficients back into a signal inside the StructureTensor.
I see that the StructureTensor dose not do the inverse transforming. Maybe I can try with the StructureTensor instead of the inverse transforming. Thanks.
Is there an Inverse Riesz transform to convert all Riesz coefficients back into a signal?
