An Approach to Image Retrieval on Fuzzy Object-Relational Databases using Dominant Color Descriptors
نویسندگان
چکیده
In this paper we introduce a fuzzy approach for image retrieval based on color features. Our method deals with two problems related to imprecision: the vagueness in the color description and the representation of fuzzy data in database models. To face the first problem, the concept of dominant fuzzy color is introduced to describe the image, using linguistic labels for representing the color information in terms of hue, saturation and intensity as humans do. To deal with fuzzy data in our database model, we use a general approach which can support the manipulation of fuzzy objects in an object-relational database system. This allows the retrieval of images by performing flexible queries on the database.

Retrieving images in fuzzy object-relational databases using dominant color descriptors
In this paper a fuzzy approach for image retrieval on the basis of color features is presented. The proposal deals with vagueness in the color description and introduces the use of fuzzy database models to store and retrieve imprecise data. To face the color description, the concept of dominant fuzzy color is proposed, using linguistic labels for representing the color information in terms of h...
متن کاملTowards a Fuzzy Object-Relational Database Model
This chapter introduces a fuzzy object-relational database model including fuzzy extensions of the basic object-relational databases constructs, the user-defined data types, and the collection types. The fuzzy extensions of these constructs focus on two main flexible aspects, a way to flexibly compare complex data types and an extension of collection types allowing partial membership of its ele...
متن کاملFlexible Retrieval of X-Ray Images Based on Shape Descriptors Using a Fuzzy Object-Relational Database
This paper presents a novel approach for medical image storage using a Fuzzy Object-Relational Database Management System (FORDBMS). The system stores medical images along with a set of parameters describing their content. Flexible queries can be performed over these parameters to retrieve images matching visually. To illustrate the capabilities of the FORDBMS, parameter curves are obtained fro...
متن کاملRanking Images Using Customized Fuzzy Dominant Color Descriptors
In this paper we describe an approach for defining customized color descriptors for image retrieval. In particular, a customized fuzzy dominant color descriptor is proposed on the basis of a finite collection of fuzzy colors designed specifically for a certain user. Fuzzy colors modeling the semantics of a color name are defined as fuzzy subsets of colors on an ordinary color space, filling the...
متن کاملSemantic Content Based Image Retrieval Using Object-Process Diagrams
The increase in accessability to on-line visual data has promoted the interest in browsing and retrieval of images from Image Databases. Current approaches assume either a text based keyword oriented approach or a visual feature based approach. The keyword approach usually provides neither layout information nor object relevence and sig-niicance in the scene. The visual feature based approach r...
