Assisted descriptor selection based on visual comparative data analysis

by Sebastian Bremm, Tatiana Von L, Jürgen Bernard, Tobias Schreck, Technische Universität Darmstadt - Proceedings of Eurographics / IEEE-VGTC Symposium on Visualization , 2011
"... Exploration and selection of data descriptors representing objects using a set of features are important components in many data analysis tasks. Usually, for a given dataset, an optimal data description does not exist, as the suitable data representation is strongly use case dependent. Many solution ..."

Our system combines automatic data analysis with interactive visualizations. By this, the system pro-vides a recommendation for suitable data descriptor selections. It supports

A critical role for the right fronto-insular cortex in switching between central-executive and default-mode networks.

by Devarajan Sridharan , † ‡ , Daniel J Levitin , Vinod Menon - Proc Natl Acad Sci USA , 2008
"... Cognitively demanding tasks that evoke activation in the brain's central-executive network (CEN) have been consistently shown to evoke decreased activation (deactivation) in the default-mode network (DMN). The neural mechanisms underlying this switch between activation and deactivation of larg ..."

causality analysis, we show that the rFIC-ACC network, and the rFIC, in particular, plays a critical and causal role in switching between the CEN and the DMN. We replicated this causal connectivity pattern in two additional experiments: (i) a visual attention ''oddball'' task and (ii) a

Analysis of the Data Quality of Audio Descriptors of environmental Sounds

by Dalibor Mitrovic, Horst Eidenberger - In Proceedings of the Fourth Special Workshop of Multimedia Semantics. Chania
"... In this paper we perform statistical data analysis of a broad set of state-of-the-art audio features and low-level MPEG-7 audio descriptors. The investigation comprises data analysis to reveal redundancies between state-of-the-art audio features and MPEG-7 audio descriptors. We introduce a novel mea ..."

A Novel Feature Descriptor Based on the Shearlet Transform

by William Robson Schwartz, Ricardo Dutra Da Silva, Larry S. Davis, Helio Pedrini - In IEEE Intl. Conference on Image Processing , 2011
"... Problems such as image classification, object detection and recog-nition rely on low-level feature descriptors to represent visual in-formation. Several feature extraction methods have been proposed, including the Histograms of Oriented Gradients (HOG), which cap-tures edge information by analyzing ..."

, signal singularities, such as edges, can be precisely detected and located in images. Based on the idea of employing histograms to estimate the distribution of edge orientations and on the accurate multi-scale analysis provided by shearlet transforms, we propose a feature descriptor called Histograms
