Semantic Image Segmentation and Object Labeling
TL;DR: A framework for simultaneous image segmentation and object labeling leading to automatic image annotation focusing on semantic analysis of images contributes to knowledge-assisted multimedia analysis and bridging the gap between semantics and low level visual features.
Using a Multimedia Ontology Infrastructure for Semantic Annotation of Multimedia Content.
Thanos Athanasiadis,Vassilis Tzouvaras,Kosmas Petridis,Frédéric Precioso,Yannis Avrithis,Yiannis Kompatsiaris +5 more
TL;DR: In this paper, the authors discuss the use of knowledge for the automatic extraction of semantic metadata from multimedia content and develop an experimentation platform that allows them to analyze multimedia content, and automatically create the associated semantic metadata, as well as to test, validate and refine the ontologies built.
Journal ArticleDOI
Image indexing and retrieval using expressive fuzzy description logics
TL;DR: A methodology for semantic indexing and retrieval of images, based on techniques of image segmentation and classification combined with fuzzy reasoning is proposed, which allows for the extraction of rich implicit knowledge used for global image classification.

Integrating Image Segmentation and Classification for Fuzzy Knowledge-Based Multimedia Indexing
Thanos Athanasiadis,Nikolaos Simou,Georgios Th. Papadopoulos,Rachid Benmokhtar,Krishna Chandramouli,Vassilis Tzouvaras,Vasileios Mezaris,Marios Phiniketos,Yannis Avrithis,Yiannis Kompatsiaris,Benoit Huet,Ebroul Izquierdo +11 more
TL;DR: This paper proposes a methodology for semantic indexing of images, based on techniques of image segmentation, classification and fuzzy reasoning, which extracts semantic description of raw multimedia content and uses it for indexing and retrieval purposes, backed up by a fuzzy knowledge repository.
Journal ArticleDOI
Semantic representation of multimedia content: Knowledge representation and semantic indexing
TL;DR: The proposed approach utilizes as input visual content analysis results, as well as analyzes and exploits associated textual annotation, in order to extract the underlying semantics, construct a semantic index and classify documents to topics, based on a unified knowledge and semantics representation model.
