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 ...
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 ...
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 ...
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, ...
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 ...
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 ...
S-GinMob: Soft-Handoff Solution for Mobile Users in Industrial Environments
(IEEE, 2011)
In current research studies and testbed deployments of sensor networks, individual sensor nodes are usually assumed to be static. However, recent applications require mobile sensor nodes, something that poses unique ...
Handoff Triggering for Wireless Sensor Networks with Performance Needs
(IEEE, 2013)
In this paper, we deal with mobility management for wireless sensor networks and we focus on the first phase of a handoff procedure which is concerned with the mechanics of measuring important parameters and initiating ...
