[Insight-users] Input Format

[Ankit Gupta]

Hi,

I am relatively new to ITK and my project involves working with dicom
images, applying image processing filters on them and viewing the output.
Currently, I am trying to apply different blur filters to dicom images. I
understand that these filters use float as the pixel type whereas dicom
files have signed short as pixel types. So, what image format should be used
(or what format should these dicom images be converted to) so as to apply
filters on them without loss of information?

I tried to take a dicom file as input and apply a resize and then a cast
filter to cast it to a float format. But by viewing the output (as a png
file), I found that a lot of information was lost and the image looked very
different. I am stuck at his point for nearly a week and can't seem to find
any solution. Any help would be greatly appreciated.

Thanks,
Ankit.
