[Insight-users] Generic Image Reader

[Andinet Enquobahrie]

Hi Sumit,

Take a look at

http://insight-journal.org/midas/handle.php?handle=1926/495

The IO classes contributed along with this paper demonstrate  how you can
determine the pixel type and then instantiate the appropriate
type of reader.  For you purpose, you will need to extend the classes to
handle color pixel types.

>CImageType2D;
