Hi,
You should use *otb::StreamingCompareImageFilter* instead of
*otb::PersistentCompareImageFilter*. The persistent filter is used
internally but it is not meant to be instanciated by the user.
A few comments also:
* calling Update() on each reader is not necessary, nor suited for
streaming processing. You can remove these updates, only keep the
update on the compareFilter.
* You don't need an intermediate ImageType::Pointer to get the readers
output. You can directly give them to the compare filter :
*compareFilter->SetInput1(movingReader->GetOutput())*
Regards,
Guillaume

Hello , I use otbStreamingCompareImageFilter to compare two images.
But I have problem when I use GetPSNR() and GetMSE() both of output is
1.79769e+308 (I think PSNR result is ... DB %).
My code.

typedefotb::PersistentCompareImageFilter<ImageType>CompareImageType;
ReaderType::PointermovingReader =ReaderType::New();
movingReader->SetFileName("images.jpg");
movingReader->Update();
ImageType::Pointero_image =movingReader->GetOutput();
ReaderType::PointermovingReader2 =ReaderType::New();
movingReader2->SetFileName("images2.jpg");
movingReader2->Update();
ImageType::Pointeru_image =movingReader2->GetOutput();
CompareImageType::PointercompareFilter =CompareImageType::New();
compareFilter->SetInput1(o_image);
compareFilter->SetInput2(u_image);
compareFilter->Update();
cout <<"MSE of two images"<<compareFilter->GetMSE()<<endl;
cout <<"PSNR of two images"<<compareFilter->GetPSNR()<<endl;
