Content based radiology image retrieval using a fuzzy rule based scalable composite descriptor
(2010)The rapid advances made in the field of radiology, the increased frequency in which oncological diseases appear, as well as the demand for regular medical checks, led to the creation of a large database of radiology ...

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 ...

A novel cellular automata based technique for visual multimedia content encryption
(Elsevier, 2010)This paper proposes a new method for visual multimedia content encryption using Cellular Automata (CA). The encryption scheme is based on the application of an attribute of the CLF XOR filter, according to which the original ...

Fast Retrieval from Image Databases via Binary Haar Wavelet Transform on the Color and Edge Directivity Descriptor
(IARIA, 2011)In this paper, we are evaluating several accelerating techniques for content-based image retrieval, suitable for the Color and Edge Directivity Descriptor (CEDD). To date, the experimental results presented in the ...
-
Text localization using standard deviation analysis of structure elements and support vector machines
(Springer, 2011)A text localization technique is required to successfully exploit document images such as technical articles and letters. The proposed method detects and extracts text areas from document images. Initially a connected ...
-
Dynamic two-stage image retrieval from large multimedia databases
(Elsevier, 2013)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, ...
-
Co.Vi.Wo.: Color Visual Words Based on Non-Predefined Size Codebooks
(IEEE, 2012)Due to the rapid development of information technology and the continuously increasing number of available multimedia data, the task of retrieving information based on visual content has become a popular subject of scientific ...
-
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 ...

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 ...
-
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 ...

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, ...

www.MMRetrieval.net: a multimodal search engine
(Association for Computing Machinery (ACM), United States, 2010)We introduce an experimental search engine for multilin- gual and multimedia information, employing a holistic web interface and enabling the use of highly distributed indices. Modalities are searched in parallel, and ...

Accelerating Image Retrieval Using Binary Haar Wavelet Transform on the Color and Edge Directivity Descriptor
(Institute of Electrical and Electronics Engineers (IEEE), United States, 2010)In this paper, a new accelerating technique for content-based image retrieval is proposed, suitable for the Color and Edge Directivity Descriptor (CEDD). To date, the experimental results presented in the literature ...
-
Automatic Image Annotation and Retrieval Using the Joint Composite Descriptor
(Institute of Electrical and Electronics Engineers (IEEE), United States, 2010)Capable tools are needed in order to successfully search and retrieve a suitable image from large image collections. Many content-based image retrieval systems employ low-level image features such as color, texture and ...
-
Content based MRSI image indexing and retrieval involving a fuzzy descriptor
(Institute of Electrical and Electronics Engineers (IEEE), United States, 2010)Magnetic resonance spectroscopic imaging (MRSI) integrates both spectroscopic and imaging methods to produce spatially localized spectra from within the sample or patient. Although MRSI is a relatively new imaging technology ...

Late fusion of compact composite descriptors for retrieval from heterogeneous image databases
(Association for Computing Machinery (ACM), United States, 2010)Compact composite descriptors (CCDs) are global image features, capturing more than one types of information at the same time in a very compact representation. Their quality has so far been evaluated in retrieval from ...
