There are multiple algorithms. For example, look up "flood fill"

Answer 2

[Image Analyst]

For what? For how to use the imfill() function in the Image Processing Toolbox? Or for the source code that it uses?

To use it, you simply do

binaryImage = imfill(binaryImage, 'holes');

If you want to know at a low level what it does, you usually can't get that info since most toolbox m-files are just wrappers that pretty quickly jump into a DLL for which they don't supply source code. You can get similar code by searching on the internet.

If you want how they fill holes in a grayscale image, then Steve gives his source (a book) on this page: http://blogs.mathworks.com/steve/2007/07/26/filling-holes-in-images/
