[Insight-users] convering *.img to *.bmp

[Luis Ibanez]

Hi Suresh,

If your input image type is unsigned short,
the values will not fit in the range of the
output pixel type: unsigned char.

In your case, all pixels will take the low
byte of the unsigned short and that will
look as a noisy image.

Please read the ITK Software Guide

   http://www.itk.org/ItkSoftwareGuide.pdf


In particular the chapter:

     "Reading and Writing Images"

and the section on intensity scaling filters,
since the solution for your problem may be
to simply use the

      RescaleIntensityImageFilter



Regards,


    Luis
