Hi
I want to perform Band Math X with a large neighborhood (> 10). I have the error describe here:
https://bugs.orfeo-toolbox.org/view.php?id=1119
So I have compile the OTB with the following change in the code, as describe in the aforementioned link.
m_SizeNeighbourhood=20; //line 69
I also modified the error message to be sure
// line 603
//Checking formulas consistency
if (m_VNotAllowedVarName.size()>0)
{
std::stringstream sstm;
sstm << "Following variables not allowed : ";
for(unsigned int i=0; i<m_VNotAllowedVarName.size(); ++i)
sstm << m_VNotAllowedVarName[i].name << " ";
sstm << "Neighborhood size: " << m_SizeNeighbourhood; // Modif fauvel
sstm << std::endl;
itkExceptionMacro(<< sstm.str());
}
After a compilation, it is still not working, I got the following error
otbcli_BandMathX -il /media/Data/Data/Sebioref/CropImages/ortho_10_470.tif -out /tmp/toto.tif -exp "mean(im1b1N50x50)" -ram 2048

So the modification seems fine, but I cannot use neighborhood order larger than 10. I check the code, but I did not see where the size of the neighborhood is checked…
If you have any idea ??
