Combining Segmentation and Classification Techniques for Fuzzy Knowledge-based Semantic Image Annotation

Modified CLPSO-based fuzzy classification System: Color Image Segmentation

Fuzzy segmentation is an effective way of segmenting out objects in images containing both random noise and varying illumination. In this paper, a modified method based on the Comprehensive Learning Particle Swarm Optimization (CLPSO) is proposed for pixel classification in HSI color space by selecting a fuzzy classification system with minimum number of fuzzy rules and minimum number of incorr...

Integrating Image Segmentation and Classification for Fuzzy Knowledge-Based Multimedia Indexing

In this paper we propose a methodology for semantic indexing of images, based on techniques of image segmentation, classification and fuzzy reasoning. The proposed knowledge-assisted analysis architecture integrates algorithms applied on three overlapping levels of semantic information: i) no semantics, i.e. segmentation based on low-level features such as color and shape, ii) mid-level semanti...

Image indexing and retrieval using expressive fuzzy description logics

The effective management and exploitation of multimedia documents requires the extraction of the underlying semantics. Multimedia analysis algorithms can produce fairly rich, though imprecise information about a multimedia document which most of the times remains unexploited. In this paper we propose a methodology for semantic indexing and retrieval of images, based on techniques of image segme...

Building and Using Knowledge Models for Semantic Image Annotation

This dissertation aims at building and using knowledge-driven models in order to improve the accuracy of automatic image annotation. Currently, many image annotation approaches are based on the automatic association between low-level or mid-level visual features and semantic concepts using machine learning techniques. Nevertheless, the only use of machine learning seems to be insufficient to br...
