Red and Green Pixel Separation

14 Sep 2010 (Updated 22 Apr 2011)

The following code can be used to separate red and green pixels from a colored image.

File Information
Description	The following code can be used to separate red and green pixels from an image. It is based on color distance transform. Some Threshold has to be provided so that its color distance is within some range to determine whether the given pixel is red or green.
Required Products	Image Processing Toolbox
MATLAB release	MATLAB 7.6 (R2008a)

14 Sep 2010	GAGAN	I have used this one for robotic purposes for identifying red or green signal ligts. One can easily detect the blue color as well using the algorithm.
14 Sep 2010	Sean de	There are a number of things wrong with this submission: -It displays and imtool and two figures of the output arguments without the ability to turn them off. -Uses double FOR loops for a two-line logical index expression -Only does red and green; why not blue? why not the ability to select what colors we want? -Takes a filename as input not a matrix and does no error checking -Does two calculations that are never used (M-LINT!!!)
