A pixel based random model to generate aggregated binary images

ABSTRACT
Traditional random models for binary images proposed in the literature show their limits in a generating satisactory way images having a desired aggregation among their components. This is because none of them is really oriented to this aim. Rather, they are generally thought to model the behaviour of the constituting elements of the images (so loosing sight of the context), or, alternatively, to model particular data structure for their representation, underestimating the fact that there is in general no semantic link between an image and its representation. This means from one hand, the impossibility to produce meaningful theoretical results on time and space average performances of different data structures used to represent binary images, and, on the other hand, in an applicative context, the difficulty to generate random images having a statistical behaviour close to that of real images. To overcome this trouble, we introduce in our paper a new random model that, starting from the traditional pixel independent model, provides the possibility to mould the image until a given aggregation level is reached. We show how the flexibility of this new model is useful in an applicative context, especially whenever it is needed to focus on subclasses of homogeneous images, as for example landuse or topographical maps.
