Detailed Description

template<class TInputImage, class TOutputImage>
class otb::LeeImageFilter< TInputImage, TOutputImage >

Anti-speckle image filter.

This class implements Lee's filter for despeckleing of SAR images. The estimated reflectivity R is computed as follows:

R=I*W+E[I]*(1-W), where W=1-Cu*Cu/(Ci*Ci) Cu = 1/sqrt(nb of look) Ci = sqrt(VAR[I])/E[I]

◆ GenerateInputRequestedRegion()

template<class TInputImage , class TOutputImage >
void otb::LeeImageFilter< TInputImage, TOutputImage >::GenerateInputRequestedRegion
override

LeeImageFilter needs a larger input requested region than the output requested region. As such, LeeImageFilter needs to provide an implementation for GenerateInputRequestedRegion() in order to inform the pipeline execution model.

overrideprotected

LeeImageFilter can be multithreaded. As such, it provides a definition of ThreadedGenerateData()

LEE filter: $ R = E[I] + b(I-E[I])$ with $ b = C^2r / ( C^2r + C^2v )$ $ Cv = 1 / \sqrt(L) $ with L the number of look. $ Cr = \sqrt(Var(I)) / E[I] where Var(I) = E[I^2] - E[I]^2 $
