<div dir="ltr"><div>Thanks Christopher,<br><br></div>I removed the VTK viewer part and instead of creating two images I edited the code to read tow ".hdr" files and write one ".hdr" output file. But I am getting the following errors. I couldn't figure out the problem. Given below is multiplyFilter.cxx code:<br>
<br>#include "itkImage.h"<br>#include "itkImageFileReader.h"<br>#include "itkImageFileWriter.h"<br>#include "itkRescaleIntensityImageFilter.h"<br>#include "itkMultiplyImageFilter.h"<br>

<p dir="ltr">This example might help. You can delete the VTK-viewer bit if you want, should only need ITK. </p>
