In the framework of an algorithm-driven random function, the L realizations define the random function; they are useful only if the process (algorithm) used for their generation reflects the joint dependence between data and unknowns. The arithmetic average of the L simulated…

…in the course of simulation. Because scanning and the search tree storage do not retain the location information, the training image should be “stationary”. That is, any particular pattern should be found at many places throughout the training image. Issues of non stationarity can be dealt with by considering separately different stationary training images, see later p.178. Details about the search tree….
