In the context of flow in porous media, up-scaling is the coarsening of a geological model and it is at the core of water resources research and reservoir simulation. An ideal up-scaling procedure preserves heterogeneities at different length-scales but reduces the computational costs of dynamic simulations.

Haar Wavelets in Data Analysis
Advanced Materials Research, 2010One century ago (1910), the Hungarian mathematician Alfred Haar introduced the simplest wavelets in approximation theory, which are now known as the Haar wavelets. This type of wavelets can effectively be used to fit data in statistical applications.

Optical Haar wavelet transform
Optical Engineering, 1992An optical Haar mother wavelet is created with a Semetex 128 x 128 magneto-optic spatial light modulator. Two techniques for dilating the mother wavelet are explored: (1) aperture stopping and (2) operating the SLM in ternary phase-amplitude mode. Discrete resolution levels of a continuous wavelet transform are obtained by optically correlating a ...

Effective and Fast DeepFake Detection Method Based on Haar Wavelet Transform
International Conference on Computer Science and Software Engineering, 2020DeepFake using Generative Adversarial Networks (GANs) tampered videos reveals a new challenge in today’s life. With the inception of GANs, generating high-quality fake videos becomes much easier and in a very realistic manner.

Volumendekorrelation durch 3D-Haar-Wavelets
2020Der Haar-Kern ist der wohl einfachste Reprasentant eines Kerns mit lokalem Trager, der durch einen Parameter τ > 0 bestimmt wird. Er wurde in die mathematische Literatur durch A. Haar (1910) im eindimensionalen Euklidischen Raum eingefuhrt.

Fingerprint verification using haar wavelet
2010 2nd International Conference on Computer Engineering and Technology, 2010This paper deals with a new image based approach for fingerprint verification using Haar Wavelet Transform. Haar wavelet is used for decomposition of the fingerprint image. Haar wavelet transformation is carried out directly on the gray-scaled fingerprint image without any preprocessing steps. Decomposition of the fingerprint image is carried out up to

Solving ordinary differential equations with higher order Haar wavelet method
CENTRAL EUROPEAN SYMPOSIUM ON THERMOPHYSICS 2019 (CEST), 2019The higher order Haar wavelet method (HOHWM) approach is proposed for solving ordinary differential equations (ODE). Different algorithms for determining complementary integration constants are considered.
