You can threshold

binaryImageRed = rgbImage(:,:,1) > someThresholdValueR;
binaryImageGreen = rgbImage(:,:,2) > someThresholdValueG;
binaryImageBlue = rgbImage(:,:,3) > someThresholdValueB;

What are you thinking would be foreground and what is background? I can't tell because you forgot to attach your image.

See my masking demo, attached.

You should use imshow() instead of disp(). imshow() displays the image while disp spews every pixel value in decimal to the command window (not what you want).

Also, I don't know what the binstring stuff is for. I'd get rid of it.

Get rid of m too. Then read this: http://www.mathworks.com/matlabcentral/answers/6200-tutorial-how-to-ask-a-question-on-answers-and-get-a-fast-answer I'll consider this discussion done unless you ask more questions.
