In this work we present an approach for the synthesis of object models (expressed as Constraint Satisfaction Problems, CSPs) from views or partial models (expressed, in their turn, as CSPs as well). The approach we propose is general enough to consider different types of features and relationships in the views. This is achieved by introducing the notion of model representation, where features, relationships and their domains are expressed. The (complete) model can be synthesized through a proper algorithm, which provides a albeling between the (complete) model and the partial models' components. The generated CSP representing the synthesized model must satisfy (or, better, entail) any constraint among features and any relationship occurring in each partial model. The framework is applied for synthesizing object models (i.e., CSP descriptions). We provide two basic approaches for synthesizing a minimal or a correct model, and we experiment them by considering some case studies in artificial vision.

Abstract
In this work we present an approach for the synthesis of object models (expressed as Constraint Satisfaction Problems, CSPs) from views or partial models (expressed, in their turn, as CSPs as well). The approach we propose is general enough to consider different types of features and relationships in the views. This is achieved by introducing the notion of model representation, where features, relationships and their domains are expressed. The (complete) model can be synthesized through a proper algorithm, which provides a albeling between the (complete) model and the partial models' components. The generated CSP representing the synthesized model must satisfy (or, better, entail) any constraint among features and any relationship occurring in each partial model. The framework is applied for synthesizing object models (i.e., CSP descriptions). We provide two basic approaches for synthesizing a minimal or a correct model, and we experiment them by considering some case studies in artificial vision.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
