Define "remove." Do you want to extract the bounding box into its own image? If so, see my BlobsDemo http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862 Or do you want to set all pixels values of 255 to 0 or nan?

Which color should the 1,1,1 pixels get set to? 0,0,0, or .478,.478,.478?
rgbImage(rgbImage==1) = 0; % Or 0.478 whichever you want.
