Hybrid Cellular Ants for Clustering Problems
(Old City Publishing, 2014)
In the last decade the amount of the stored data related to almost all areas of life has rapidly increased. However, the overall process of discovering knowledge from data demands more powerful clustering techniques to ...
Image Encryption using the Recursive Attributes of the eXclusive-OR Filter
(Springer, 2014)
This paper describes a visual multimedia content encryption approach
based on cellular automata (CA), expanding the work
proposed in [4]. The presented algorithm relies on an attribute
of the eXclusive-OR (XOR) filter, ...
Multimedia Search with Noisy Modalities: Fusion and Multistage Retrieval
(ImageClef, Wikipedia Retrieval Task, 2010)
We report our experiences from participating to the controlled experiment of the ImageCLEF 2010 Wikipedia Retrieval task. We built an experimental search engine which combines multilingual and multi-image search, employing ...
Dynamic Two-Stage Image Retrieval from Large Multimodal Databases
(Springer-Verlag, 2011)
Content-based image retrieval (CBIR) with global features is notoriously noisy, especially for image queries with low percentages of relevant images in a collection. Moreover, CBIR typically ranks the whole collection, ...
Fusion vs. Two-Stage for Multimodal Retrieval
(Springer, 2011)
We compare two methods for retrieval from multimodal collections.
The first is a score-based fusion of results, retrieved visually and textually. The
second is a two-stage method that visually re-ranks the top-K results ...
Bag-of-visual-words vs global image descriptors on two-stage multimodal retrieval
(ACM SIGIR 2011, 2011)
The Bag-Of-Visual-Words (BOVW) paradigm is fast becoming a
popular image representation for Content-Based Image Retrieval
(CBIR), mainly because of its better retrieval effectiveness over
global feature representations ...
Comparative Performance Evaluation of Image Descriptors Over IEEE 802.11b NoisyWireless Networks
(IEEE (Computer Society), 2011)
Abstract—In this paper we evaluate the image retrieval
procedure over an IEEE 802.11b Ad Hoc network, operating
in 2.4GHz, using IEEE Distributed Coordination Function
CSMA/CA as the multiple access scheme. IEEE 802.11 ...
Mean Normalized Retrieval Order (MNRO): a new content-based image retrieval performance measure
(Springer, 2014)
The results of a content based image retrieval system can be evaluated by several performance measures, each one employing different evaluation criteria. Many of the methods used in the field of information retrieval have ...
Accurate Image Retrieval Based on Compact Composite Descriptors and Relevance Feedback Information
(World Scientific Publishing Company, 2010)
In this paper a new set of descriptors appropriate for image indexing and retrieval is proposed.
The proposed descriptors address the tremendously increased need for e±cient content-based
image retrieval (CBIR) in many ...
Investigating the Behavior of Compact Composite Descriptors in Early Fusion, Late Fusion and Distributed Image Retrieval
(2010)
In Content-Based Image Retrieval (CBIR) systems, the visual content of the images is mapped into a new space named the feature space. The features that are chosen must be discriminative and sufficient for the description ...
