In this article, we present the first method to generate plausible sounds while animating crumpling virtual paper in real time. Our method handles shape-dependent friction and crumpling sounds which typically occur when manipulating or creasing paper by hand. Based on a run-time geometric analysis of the deforming surface, we identify resonating regions characterizing the sound being produced. ...

3D scene classification has become an important research field in photogrammetry, remote sensing, computer vision and robotics with the widespread usage of point clouds. Point cloud classification, called semantic labeling, segmentation, or clouds is a challenging topic. Machine learning, on other hand, powerful mathematical tool used to classify whose content can be significantly complex. In t...

In order to accelerate computations and improve long time accuracy of numerical simulations, this thesis develops multiscale geometric integrators. For general multiscale stiff ODEs, SDEs, and PDEs, FLow AVeraging integratORs (FLAVORs) have been proposed for the coarse time-stepping without any identification of the slow or the fast variables. In the special case of deterministic and stochastic...

In this paper, we perform a systematic multiscale analysis for the three-dimensional incompressible Navier–Stokes equations with multiscale initial data. There are two main ingredients in our multiscale method. The first one is that we reparameterize the initial data in the Fourier space into a formal two-scale structure. The second one is the use of a nested multiscale expansion together with ...

The diagrammatic summary of the suggested multiscale modeling approach and its steps is presented in Figure S1. All the details of the UFF force fields [1–3] used for P3HT, P3BT, and PCBM molecules can be found in Tables S1 and S2, respectively, while numerical labels of all the interaction sites can be identified from Figure S2. Plots of 1D-RDFs of selected interaction sites are displayed in F...

The total variation based image denoising model of Rudin, Osher, and Fatemi has been generalized and modified in many ways in the literature; one of these modifications is to use the L1 norm as the fidelity term. We study the interesting consequences of this modification, especially from the point of view of geometric properties of its solutions. It turns out to have interesting new implication...

We introduce a new model for multiscale analysis of space-time echocardiographic sequences. The proposed nonlinear partial diierential equation, representing the multiscale analysis, lters the sequence with keeping of the space-time coherent structures. It combines the ideas of regularized Perona-Malik anisotropic diiusion and Galilean invariant movie multiscale analysis of Alvarez, Guichard, L...

ABSTRACT The study aimed to characterize the spatial structure of variability biophysical indexes vegetation through images obtained by Unmanned Aerial Vehicles under strong heterogeneity and anisotropy, using geostatistical procedures. Plots with different types densities culture were evaluated in a didactic vegetable garden. Five from aerial multispectral camera parallel analysis anisotropy i...
