In your case, the background is white. So you already have a background mask and you just need to tell us what "remove" means to you. Do you want to blacken it in the original image? If so, just do
% Mask the image using bsxfun() function to multiply the mask by each channel individually.
maskedRgbImage = bsxfun(@times, rgbImage, cast(~mask, 'like', rgbImage));
You can also use a gray scale image instead of rgbImage in the above code. Or, simply do
grayImage(mask) = 0;

Did you see at the bottom of Steve's blog where it said "Get the MATLAB code"? If you click on that, it will run a javascript and all the code for the watershed is there. Of course, I don't know if it's exactly the process done in your paper so you might have to compare and use whichever one you want if they're different.
