Please look at the "projection along an axis" contribution to the insight  
journal
http://insight-journal.org/InsightJournalManager/view_reviews.php?back=publications.php%3Fjournalid%3D4%26order%3Drating%26revision_display%3Dcombined&pubid=71

You can also find it in ITK cvs.

That's right that many filters are missing to perform simple tasks.
ITK is open source, and open to contributions. Feel free to contribute  
contribute new code to the insight journal :-)
