You could divide the image into subregions via the "splitter" functions in ITK. Then iterate each subregion, place the values in a std vector, sort, and find the median. <br><br><div class="gmail_quote">2011/6/24 Françoise Lefebvre <span dir="ltr"><<a href="mailto:lefebvre@imnc.in2p3.fr">lefebvre@imnc.in2p3.fr</a>></span><br>

Hi,<br>
<br>
Is there a simple method to compute the median of the values over a given rectangular region from an image. The MedianImageFunction only computes it over the standard 8, 26, etc. connected neighborhood of a pixel.<br>
<br>
Thank you in advance<br>
