An open source toolbox for Sound Field Synthesis (SFS) is introduced. The toolbox is able to numerically simulate sound fields synthesized by SFS methods like Wave Field Synthesis or higher order Ambisonics. Various loudspeaker driving signals for the mentioned methods are provided for 2-, 2.5and 3-dimensional synthesis. The toolbox allows mono-frequent as well as broadband excitation signals. ...

This paper addresses face recognition under varying light via 3D reconstruction based on the techniques of shape from shading (SFS). First, we improve the geometric-based SFS by introducing the integrability constraint as one of the regular terms. This operation preserves the local curvedness of the recovered surface. Second, we propose a novel method to investigate human face recognition in th...

High performance Mg-8.2Gd-3.8Y-1.0Zn-0.4Zr alloy with high strength and excellent ductility has been successfully developed by hot extrusion. The effect of plate-shaped long period stacking ordered (LPSO) phases and solute-segregated stacking faults (SFs) on the dynamically recrystallization (DRX) behavior was analyzed. The plate-shaped LPSO phases stimulate the DRX by particle stimulated nucle...

Shape from Shading (SFS) is one of the most extensively studied problems in Computer Vision. However, most of the approaches only deal with Lambertian or other specific shading models, and are hence limited in their applicability to real images. In this contribution we propose a general unified framework in which it is possible to incorporate different illumination and shading models. We effect...

The problem of acquiring surface models of faces is an important one with potentially significant applications in biometrics, computer games and production graphics. For such task, the use of shape-from-shading (SFS) is appealing since it is a non-invasive method that mimics the capabilities of the human visual system. In this thesis, our interest lies on the recovery of facial shape from singl...

Sir: We recently published an algorithm based on combinations of synovial fluid (SF) cell number thresholds and types which should considerably extend the diagnostic use of SF cytology in non-septic/crystal arthritis.' Key branch points depend on accurate values for total and differential nucleated leucocyte counts (white cell count (WCC)), ragocytes, and Reiter's cells (cyto-phagocytic mononuc...

In this paper the effects of polarimetry on the Synthetic Aperture Radar (SAR) shape-from-shading (SfS) technique developed by the authors are analysed and discussed. In particular, the validity of some hypotheses, on which the method is based, is investigated for the different polarization channels and their influence on the accuracy of the proposed SfS technique is discussed. The paper conclu...

A dynamic eddy viscosity (DEV) model and a constant (CEV) are proposed for stabilizing the temporal direct deconvolution (TDDM) in large-eddy simulation of turbulence. Compared to original unresolved subfilter-scale used TDDM, new models reduce number empirical coefficients make TDDM more convenient be applied practice. The DEV does not have any coefficients, CEV has only one coefficient that i...
