These operations are the building blocks of the algorithms we are to explore. By themselves, they beautifully illustrate the basic principle of mathematical imaging. An image is represented as a mathematical object and, as such, basic operations on the corresponding object can be translated to either physical operations or queries on the corresponding image.
