This article [J. Electron. Imaging, 18, 023009 (2009)] was originally published online on 15 May 2009 with an error on page 11, in the first author biography. The first author's name originally appeared here as “Chen-Chin Tsai.” It should read “Chung-Chih Tsai” as per the author affiliations on page 1.
