<DIV id=RTEContent> <DIV id=RTEContent>well again the code appeared seperately, here is the text part.... </DIV> <DIV> </DIV> <DIV> </DIV> <DIV>Hi all,</DIV> <DIV> </DIV> <DIV>First of all I would like to thank everybody especially Luis for the prompt answers! Thank you very much!</DIV> <DIV> </DIV> <DIV>Secondly, questions :-)</DIV> <DIV> </DIV> <DIV>I attached my code and 4 kidney images</DIV> <DIV> </DIV> <DIV>For the images:</DIV> <DIV><A href="http://www.mypacs.net/cgi-bin/repos/mpv3_repo/wrm/repo-view.pl?cx_subject=3220582&cx_image_only_mode=off&cx_repo=mpv4_repo&cx_from_folder" target=_blank><U><FONT color=#003399>http://www.mypacs.net/cgi-bin/repos/mpv3_repo/wrm/repo-view.pl?cx_subject=3220582&cx_image_only_mode=off&cx_repo=mpv4_repo&cx_from_folder</FONT></U></A>=</DIV> <DIV> </DIV> <DIV>here is what I want to do: </DIV> <DIV>differenceImage = (im1+im2) - (im15+im26)</DIV> <DIV> </DIV>
<DIV>However, the difference images appears as black&white, why? Could you inform me more on what the RescaleIntensityImageFilter does? If what it does is:</DIV> <DIV> </DIV> <DIV> image - min( image )</DIV> <DIV>RescaledImage = 255 * -------------------------------------</DIV> <DIV> max(image) - min( image )</DIV> <DIV> </DIV> <DIV>then definitely I should have some values in between not just zero and
255 -- shouldn't I? </DIV> <DIV> </DIV> <DIV>If this is not what it does, then can you please tell me what else to use? </DIV> <DIV> </DIV> <DIV>Thanks a lot!</DIV> <DIV>seniha</DIV></DIV><BR><BR><DIV>Seniha Esen Yuksel <BR>Research Assistant <BR>Computer Vision and Image Processing Lab, <BR>Lutz Hall Rm 414, <BR>University of Louisville, <BR>Louisville, KY <BR>work ph: 502- 8521528 <BR>home ph: 502- 8549856 <BR>email: esen@cvip.uofl.edu // esenyuksel@ieee.org <BR>web: <A href="http://www.cvip.louisville.edu/~esen/">http://www.cvip.louisville.edu/~esen/</A></DIV><p>
