Real-time indexing for large image databases: color and edge directivity descriptor on GPU
(Springer, 2014)
In this paper, we focus on implementing the extraction of a well-known low-level image descriptor using the multicore power provided by general-purpose graphic processing units (GPGPUs). The color and edge directivity ...
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 ...
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 ...
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 ...
