[ITK] [ITK-users] Error while reading Unknown Image Information

[Matt McCormick]

Hi Sarthak,

It looks like a good improvement.

The ImageIO's classes for the different file formats must be
registered to the factory.  When using CMake to configure your
project, this is done automatically.  When not using CMake, it must be
done manually.  Are you using CMake to configure your project?

HTH,
Matt
