Multiple Sound Source Localization with Rigid Spherical Microphone Arrays via Residual Energy Test
Coteli, Mert Burkay; Hacıhabiboğlu, Hüseyin (2019-05-01)
The estimation of the directions-of-arrival (DOAs) of multiple sound sources is a fundamental stage in acoustic scene analysis. Many application areas such as robot audition and object-based audio (OBA) broadcast require that DOA estimation is computationally efficient to allow real-time operation. We propose a new DOA estimation approach based on a sparse representation of recorded sound fields as a linear combination of spatially bandlimited impulses in this paper. The proposed algorithm operates on a tim...
Disconnected skeletons for shape recognition
Aslan, Çağrı; Adalı, Orhan; Department of Computer Engineering (2005)
This study presents a new shape representation scheme based on disconnected symmetry axes along with a matching framework to address the problem of generic shape recognition. The main idea is to define the relative spatial arrangement of local symmetry axes in a shape centered coordinate frame. The resulting descriptions are invariant to scale, rotation, small changes in viewpoint and articulations. Symmetry points are extracted from a surface whose level curves roughly mimic the motion by curvature. By inc...
Single-molecule-resolution ultrafast near-field optical microscopy via plasmon lifetime extension
Ovalı, Rasim Volga ; Şahin, Ramazan; Bek, Alpan; Taşgın, Mehmet Emre (2021-06-14)
Metal nanostructures support plasmon oscillations on their surfaces, which normally decay very quickly. Nevertheless, the lifetime of these oscillations can be extended near a longer lifetime particle, e.g., a molecule. We utilize this phenomenon for ultrahigh (single-molecule) resolution ultrafast apertureless (scattering) applications. We demonstrate the phenomenon with the numerical solutions of 3D Maxwell equations. We use a nm-sized quantum emitter (QE) for the long lifetime particle. We place the QE a...
Multi-view video coding via dense depth estimation
Oezkalayci, Burak; Gedik, O. Serdar; Alatan, Abdullah Aydın (2007-05-09)
A geometry-based multi-view video coding (MVC) method is proposed. In order to utilize the spatial redundancies between multiple views, the scene geometry is estimated as dense depth maps. The dense depth estimation problem is modeled by using a Markov random field (MRF) and solved via the belief propagation algorithm. Relying on these depth maps of the scene, novel view estimates of the intermediate views of the multi-view set is obtained with a 3D warping algorithm, which also performs hole-filling in the...
