I am working on image segmentation depending upon color detection, a code was sent to me including a certain range of color tones it does not work well. and I am searching for help right now.
if true
(C >= 11.64 && C <= 27.82) && (H >= 36.17 && H <= 64.17) && (L >= 32.49 && L <= 73.46)
end

The syntax looks wrong.
Try perhaps:
if (C >= 11.64 && C <= 27.82) && (H >= 36.17 && H <= 64.17) && (L >= 32.49 && L <= 73.46)
% Do stuff
else
% Do alternative stuff
end
.

syntax is not wrong, I wrote it that way to note the segmentation condition nothing else

Try the Color Thresholder on the Apps tab of the tool ribbon to find the values.
Or try the color segmentation demos in my File Exchange: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862
and see the other attached demo that works for skin on the demo image that ships with MATLAB.
Finally, see the skin gamut with the skin_color.m demo (attached) to see why simple thresholding in any color space will not get you all skin colors for all Fitzpatrick skin types.
