A comparative study of map building techniques by processing sonar arc-maps
(2005)In this study, four signal processing schemes regarding sonar sensor based map-building applications were compared. The newly proposed method, Directional Maximum is found to be successful in terms of reducing the innate ... -
Compressive sensing based flame detection in infrared videos
(2013)In this paper, a Compressive Sensing based feature extraction algorithm is proposed for flame detection using infrared cameras. First, bright and moving regions in videos are detected. Then the videos are divided into ... -
A computational homogenization framework for soft elastohydrodynamic lubrication
(Springer-Verlag, 2012)The interaction between microscopically rough surfaces and hydrodynamic thin film lubrication is investigated under the assumption of finite deformations. Within a coupled micro-macro analysis setting, the influence of ... -
Exact diffraction calculation from fields specified over arbitrary curved surfaces
(Elsevier, 2011-07-30)Calculation of the scalar diffraction field over the entire space from a given field over a surface is an important problem in computer generated holography. A straightforward approach to compute the diffraction field from ... -
A five-level static cache architecture for web search engines
(Elsevier Ltd, 2012)Caching is a crucial performance component of large-scale web search engines, as it greatly helps reducing average query response times and query processing workloads on backend search clusters. In this paper, we describe ... -
Human activity recognition using inertial/magnetic sensor units
(2010)This paper provides a comparative study on the different techniques of classifying human activities that are performed using body-worn miniature inertial and magnetic sensors. The classification techniques implemented and ... -
Man-made object classification in SAR images using 2-D cepstrum
(2009)In this paper, a novel descriptive feature parameter extraction method from Synthetic Aperture Radar (SAR) images is proposed. The new method is based on the two-dimensional (2-D) real cepstrum. This novel 2-D cepstrum ... -
Online classification with contextual exponential weights for disease diagnostics
(Institute of Electrical and Electronics Engineers Inc., 2017)In this paper, a novel online scheme for classification, which is based on the contextual-variant of Weighted Average Forecaster Algorithm is proposed. The proposed method adaptively partitions the data space based on ... -
PO-MLFMA hybrid technique for the solution of electromagnetic scattering problems involving complex targets
(2007)The multilevel fast multipole algorithm (MLFMA) is a powerful tool for efficient and accurate solutions of electromagnetic scattering problems involving large and complicated structures. On the other hand, it is still ... -
Region covariance descriptors calculated over the salient points for target tracking
(2012)Features extracted at salient points in the image are used to construct region covariance descriptor (RCD) for target tracking purposes. In the classical approach, the RCD is computed by using the features at each pixel ... -
Scene classification with random forests and object and color distributions
(2013)We propose a method to recognize the scene of an image by finding the objects and the colors it contains. We approach this problem by creating a binary vector of detected objects and a histogram of the colors that the image ... -
Target detection in SAR images using codifference and directional filters
(2010)Target detection in SAR images using region covariance (RC) and codifference methods is shown to be accurate despite the high computational cost. The proposed method uses directional filters in order to decrease the search ...
