Multiscale Analysis of Large Complex Arrays [PDF]
, 2004 Array modeling issues are challenging, since they involve large structures (in terms of the wavelength), but also fine details that require much-smaller than wavelength discretizations, and that dominate the frequency response of input parameters.

Multiscale Analysis of Accelerated Gradient Methods [PDF]
SIAM Journal on Optimization, 2020 Accelerated gradient descent iterations are widely used in optimization. It is known that, in the continuous-time limit, these iterations converge to a second-order differential equation which we refer to as the accelerated gradient flow. Using geometric singular perturbation theory, we show that, under certain conditions, the accelerated gradient flow

Multiscale Analysis of Cement Composites
Computer Assisted Methods in Engineering and ScienceThis paper is devoted to multiscale modeling of cement composites. The need for such an approach is due to the heterogeneous complex internal structure of the composite. A multiscale model of the composite was built and the results of computer simulations for the adopted parameters of the microstructure of the composite were presented, enabling a more ...

Multiscale Approach to Image Sequence Analysis
Computer Vision and Image Understanding, 1997 In optic flow based velocity estimation the image brightness constraint equation is used. However, for measurements performed at a certain scale, the brightness constraint equation does not apply. We therefore use a recently developed approach which reconciles optic flow and scale space theory. It specifically incorporates the scale (aperture) of image

A Multiscale Topographical Analysis Based on Morphological Information: The HEVC Multiscale Decomposition [PDF]
Materials, 2020 In this paper, we evaluate the effect of scale analysis as well as the filtering process on the performances of an original compressed-domain classifier in the field of material surface topographies classification. Each surface profile is multiscale analyzed by using a Gaussian Filter analyzing method to be decomposed into three multiscale filtered ...

Multiscale analysis for higher-order tensors
Wavelets and Sparsity XVIII, 2019 The widespread use of multisensor technology and the emergence of big datasets have created the need to develop tools to reduce, approximate, and classify large and multimodal data such as higher-order tensors. While early approaches focused on matrix and vector based methods to represent these higher-order data, more recently it has been shown that ...
