Ingrained

Introductionlementary probability theory and other fields with which the reader is perhaps not perfectly familiar. She or he should not worry about that — all concepts will be made thoroughly precise where they are needed.

玩忽職守

Random Fieldst a deeper understanding, in particular of topics like texture, parameter estimation or parallel algorithms, requires some abstract background and therefore one has to learn random fields. In this chapter, we present some basic notions and elementary results.

Sampling and Annealingin imaging like the computation of MMS or MPM estimators. The reader may (and is encouraged to) perform own computer experiments with these algorithms. He or she may get some ideas from the appendix which provides the necessary tools.

Eulogy

Metropolis Algorithmsand many states these methods usually are preferable. Metropolis methods are not restricted to product spaces and therefore lend themselves to many applications outside imaging, for example in combinatorial optimization. Related and more general samplers will be described as well.

This technique is adopted in most of the cited papers. Relaxation may also be introduced in continuous space and continuous time and then sampling and annealing
