Thank you both once again. According to the documentation and in practise, "-colorize N" doesn't need a percent sign. Adding a percent sign seems harmless. I did fluff my final command: the mask should be the negative of what I created, ie my "-negative" was wrong. So this is what I get (Windows ...

You did not do all the steps to change colors that are close enough replacing them with none. Or do I misunderstand what you did. convert image -fuzz XX% -fill none -opaque color1 tmpimage convert tempimage -fuzz XX% -fill none -opaque color2 tmpimage ... convert tempimage -fuzz XX% -fill none ...

Thank you both very much for your help. I have some issues (most likely I'm doing something wrong). In both cases I get an unexpected result after the final step. fwm42: Assuming tempimage == tmpimage and othercolor is my "missing" colour, I get this after the final step: http://db.tt/BzdN4b2z ...

Hi all - I'm working with an image segmentation program that requires that one type of object/region does be identified as "not of interest".

Thank you once again. I really appreciate all the help - I'm a bit lost as I'm new to both IM and bash scripting, so just trying to wrap my head around all this.

Your mapcolors looks perfect. Do you have any ideas on how I might list all the colors present in a set of images?

Thank you very much - I'm looking at your scripts now.

To answer the question, each blob is a single color and none of the blobs touch. Is this what you meant?

Hi all - sorry if this has been asked before, but I couldn't find an answer using search. I'm using Imagemagick on Linux (Xubuntu). I have a folder of pngs (named with numbers, e.g., 3096.png) which are just colored blobs on a transparent background. The blobs are different colors, with several ...
