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.
Advanced mode also displays some colorspace conversions (HSV, YCbCr, L*a*b*) of the image.
Click on any image to expand it and then right-click to export image to base workspace.
Shift-Click to generate Command-Line MATLAB code!
This is a very simple but useful utility for deciding, for instance, how you want to process/segment a color image.

Now includes Shift-click capabilities to generate MATLAB code at the Command Line!
Now incorporates toggling from normal to advanced mode, to show or hide colorspace conversions.
Better image import, better exportability, better default behavior...
2/1/11 Minor modification to provide a handle to the window; facilitates closing or referring to exploreRGB window.
Somehow, my previous attempt to update to include "advanced mode" failed. Trying again. Also, changing the image to show advanced-mode.

Expande "mode" control--now allows 'Simple" mode, with suppression of export capabilities, and 'Advanced' mode, with additional viewing of HSV, LAB, and YCbCr conversion spaces.
