Hello everybody
i have a problem and it would be great if someone helps i am trying to cut a color from an image where the result image is BW .and the color specified i want to chose is black and the rest is white .the main problem is since there was more light of the left side of the image the pixel value pattern changes for the same color over the same image,for example blue of the left has value of RGB= 106 156 183 where on the right side RGB=106 126 133 ,is there a way where i can make the brightness the same all over the image ?I mean a way of making the values of the color i see to have the same values all over the image or a same pattern?

See color segmentation demos in my File Exchange. http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862
Or use the ColorThresholder App on the Apps tab of the tool ribbon.

If you don't want to do calibrated color analysis then you can filter on whatever you have. I do that in several different ways (different color spaces) in my File Exchange: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862.
Or you can try the Color Thresholder on the Apps tab of the MATLAB tool ribbon.
