Describing Images Using Qualitative Models and Description Logics
نویسندگان
چکیده
Our approach describes any digital image qualitatively by detecting regions/objects inside it and describing their visual characteristics (shape and colour) and their spatial characteristics (orientation and topology) by means of qualitative models. The description obtained is translated into a description logic (DL) based ontology, which gives a formal and explicit meaning to the qualitative tags representing the visual features of the objects in the image and the spatial relations between them. For any image, our approach obtains a set of individuals that are classified using a DL reasoner according to the descriptions of our ontology.

A Qualitative Model for Reasoning about 3D Objects using Depth and Different Perspectives
A qualitative model for describing 3D objects (Q3D) using depth and different perspectives is presented in this paper. The front, right and up perspectives are considered as canonical. The Q3D model allow reasoning through logics defined to test the consistency of descriptions. The maximal volume of the object is also obtained logically using its Q3D description. Moreover, this model infers som...
متن کاملUsing Description Logics for Consistency-based Diagnosis
Using quantitative models of simple mechanisms as an example domain, we show how the basic principles of consistency-based diagnosis can be implemented using description logics with expressive concrete domains. In addition, description logics provide the inference services necessary to organize and validate model libraries, an aspect that is neglected in consistency-based diagnosis until now. 1...
متن کاملAn Approach for Scene Interpretation Using Qualitative Descriptors, Semantics, and Domain Knowledge
An approach for cognitive scene interpretation is proposed based on qualitative descriptors, domain knowledge and spatial logics. Qualitative descriptors of shape, colour, topology and location are used for describing any object in the scene. Two kinds of domain knowledge are provided: (i) categorizations of objects according to their qualitative descriptors, and (ii) information about target o...
متن کاملDescribing Images using a Multilayer Framework based on Qualitative Spatial Models
To date most research in image processing has been based on quantitative representations of image features using pixel values, however, humans often use abstract and semantic knowledge to describe and analyze images. To enhance cognitive adequacy and tractability, we here present amultilayer framework based on qualitative spatial models. The layout features of segmented images are defined by qu...
متن کاملSBox: A Qualitative Spatial Reasoner –Progress Report–
This paper presents a method for reasoning about spatial objects and their qualitative spatial relationships (e.g. touches, overlaps etc.) on the basis of a description logic framework. We apply this method to the domain of deductive geographic information systems. In contrast to existing work, which mainly focuses on reasoning about qualitative spatial relations alone, we integrate quantitativ...
