Recursive Compositional Models (RCMs) are class of hierarchical
probabilistic models of images and objects. Visual structures are
represented in a hierarchical form where complex structures are composed of
more elementary structures following a design principle of recursive
composition.

Probabilities are defined over these structures which exploit properties of
the hierarchy (e.g. long range spatial relationships can be represented by
local potentials at the upper levels of the hierarchy). The compositional
nature of this representation enables efficient learning and inference
algorithms. Hence the overall architecture of RCMs provides a balance
between statistical and computational complexity.
We describe applications of these methods to a range of different vision
problems. We show that the performance of these hierarchical methods is
generally state of the art when evaluated on benchmarked datasets which
validates the promise of this class of models.
