Deals with a specific approach currently tested in the authors'laboratory, relative to the development of an user oriented interfacededicated to image processing (IP). The main concern is to integratedifferent classes of IP methods into a programming environment whichallows various IP concepts to be handled. It is possible to describe analgorithm using associative mechanisms on abstract objects includinginheritance of their properties from top to bottom and to store it intoan IP database. Each treatment to be included in the programmingenvironment gets a hierarchical functional representation; it is thendefined as a graph linking some operators working on a set of basic IPobjects and carrying IP properties. This kind of `standardization' helpsto classify, select, modify or create operators. This way anytheoretical model implicity embedded in an IP algorithm could bedescribed in terms of its properties, so the propose a semantic approachaiming to capture the `a priori' knowledge about, for instance,applications in taking into account the hierarchical links betweenmodels and patterns, patterns and operator properties then propertiesand access criteria
