Multimedia Retrieval Through Unsupervised Hypergraph-Based Manifold Ranking

IEEE Transactions on Image Processing, 2019
Accurately ranking images and multimedia objects are of paramount relevance in many retrieval and learning tasks. Manifold learning methods have been investigated for ranking mainly due to their capacity of taking into account the intrinsic global ...

Multimedia document retrieval

Information Processing & Management, 1995
Abstract This study develops an integrated conceptual representation scheme for multimedia documents that are viewed to comprise an object-oriented database. It develops the necessary abstractions for the conceptual model and extensions to the RM/T relational model used as the search structure. It then develops a retrieval model in which the database

Multimedia Information Retrieval

2021
Due to increasing globalization and the explosion of media available on the Internet, computer techniques to organize, classify, and find desired media are becoming more and more relevant. One such technique to extract semantic information from multimedia data sources is Multimedia Information Retrieval (MMIR or MIR).

Multimedia information retrieval

ACM SIGIR Forum, 2007
With the rising popularity of rich media services such as Flickr, YouTube, and Jumpcut, new challenges in large scale multimedia information retrieval have emerged that not only rely on meta-data but on content-based information retrieval combined with the collective knowledge of users and geo-referenced meta-data that is captured during the creation ...

Multimedia Information Retrieval

itit, 2009
Zusammenfassung Der Umfang, in dem multimediale Daten verfügbar sind, nimmt ständig zu. Dies gilt für das Internet ebenso wie für die Daten auf dem heimischen PC oder auch auf einem PDA. Eine wesentliche Herausforderung stellt dabei die Suche nach Medienobjekten dar.

Differentially-Private and Trustworthy Online Social Multimedia Big Data Retrieval in Edge Computing

IEEE transactions on multimedia, 2019
The explosive growth of multimedia contents (MCs) in today's mobile social networks has pushed edge computing to face severe security and online big data-processing problems. On the one hand, the edge nodes (ENs) should help mobile users find, cache, and

Multimedia retrieval benchmarks

IEEE Multimedia, 2004
Multimedia retrieval systems' development has long been challenged by the lack of standard benchmarks for evaluating and comparing the performance of emerging techniques. However, two recent benchmarking efforts, TREC Video Retrieval Evaluation (TRECVID) and the IAPR TC-12 Benchmark for Visual Information Search, show great promise for letting the ...

Multimedia Information Retrieval

Proceedings of the ACM Multimedia Asia, 2019
My main research interests include product search and visual question answering (VQA), lying in the field of information retrieval (IR), which aims to obtain information system resources relevant to an information need from a collection. Product search focuses on the E-commerce domain and aims to retrieve products which are not only relevant to the ...
