exploreRGB

Simple utility to view (in subplots of a figure) all color planes, and grayscale and RGB versions, o

Description

Takes as an input an RGB image (or the name/path of an RGB image) and creates a figure in which you can see side-by-side the original, the grayscale (RGB2GRAY), and the individual R,G, and B color planes.

This is a very simple but useful utility for deciding, for instance, how you want to process/segment a color image.

• Required Products: Image Processing Toolbox
• MATLAB release: MATLAB 7.6 (R2008a)

I love this. This is a great tool for showing people RGB concepts. I love how this displays the images in such an elegant layout.

Great function, except the "mode control" does not seem to be in the updated code. The file I downloaded only has a date of 4/24/2008.

Hi Paul,
Thanks very much for drawing my attention to this problem. The file is marked with a modification date of 6/21/10, but the associated code predates that. I don't know why that is, but I will look into how that happened, and I will make sure to put the more recent code on the File Exchange. In the meantime, I would be more than happy to email you a copy of the updated version of exploreRGB. (Just let me know.)
By the way, how did you happen to find your way to exploreRGB today, if you don't mind my asking?
Regards,
Brett

Hi all,
A few people have contacted me to let me know that this version is not the same as that shown on my guest blog on "Steve on Image Processing." I'm not sure why this function wasn't updated, but I recently re-submitted my modifications; it should be up shortly. In the meantime, if anyone wants to email me directly at char(cumsum([98 16 -13 15 0 -70 69 -11 7 -10 7 7 -4 -1 -46 45 -12 19 -12 15 -8 3 -7 8 -69 53 12 -2])), I will be happy to send the updated file via email.
Cheers,
Brett

As of today, the new code is live herein. Thanks for the interest!

PLEASE NOTE: To use the new version, you will need to EITHER download EXPANDAXES (http://www.mathworks.com/matlabcentral/fileexchange/18291-expandaxes) OR comment out the corresponding line (line 173). (I recommend the former!)
Cheers,
Brett

Brett -
I found explore RGB because I was attempting to replicate your code on Steve's blog.
