One trick that is used when displaying differences between two images is to rebase the image so that the "zero" color is actually <tt>#808080</tt>. Then you can show differences that are both positive and negative. –[[User:Dkf|Donal Fellows]] 11:08, 29 December 2009 (UTC) |

::I just suggested it because I encountered the concept when I solved the [[Image convolution]] task. I'm not very surprised that it didn't produce an interesting image though; the two images don't differ all that much. (I didn't even try to do a visual difference for image difference task, and instead took my cue from the other solutions.) –[[User:Dkf|Donal Fellows]] 10:50, 31 December 2009 (UTC) |
