Exponential Methods for Anisotropic Diffusion
, 2023 The anisotropic diffusion equation is imperative in understanding cosmic ray diffusion across the Galaxy, the heliosphere, and its interplay with the ambient magnetic field. This diffusion term contributes to the highly stiff nature of the CR transport equation.

Adaptive pre-filtering techniques for colour image analysis [PDF]
, 2007 One important step in the process of colour image segmentation is to reduce the errors caused by image noise and local colour inhomogeneities. This can be achieved by filtering the data with a smoothing operator that eliminates the noise and the ...

A robust anisotropic diffusion filter with low arithmetic complexity for images
EURASIP Journal on Image and Video Processing, 2019 Image smoothing with edge preservation in the presence of outliers is a challenge in image processing. Anisotropic diffusion smoothing is a well-established paradigm in digital image smoothing with edge preservation.

Moroccan Journal of Pure and Applied Analysis, 2021 We introduce a new non-overlapping optimized Schwarz method for fully anisotropic diffusion problems. Optimized Schwarz methods take into account the underlying physical properties of the problem at hand in the transmission conditions, and are thus ...

Selection Theory of Dendritic Growth with Anisotropic Diffusion
Advances in Condensed Matter Physics, 2015 Dendritic patterns frequently arise when a crystal grows into its own undercooled melt. Latent heat released at the two-phase boundary is removed by some transport mechanism, and often the problem can be described by a simple diffusion model.

Experimental Investigation of Anisotropic Diffusion Applied in Ghost Imaging Reconstruction
Applied Sciences, 2020 In iterative pseudo-inverse ghost imaging (IPGI), how much the noise interference item of the current iteration approximates the real noise greatly depends on the clarity of initial image.

Dynamic properties of two-dimensional latticed holographic system
Journal of High Energy Physics, 2022 We study the anisotropic properties of dynamical quantities: direct current (DC) conductivity, butterfly velocity, and charge diffusion. The anisotropy plays a crucial role in determining the phase structure of the two-lattice system.

Image statistics and anisotropic diffusion [PDF]
Proceedings Ninth IEEE International Conference on Computer Vision, 2003 Many sensing techniques and image processing applications are characterized by noisy, or corrupted, image data. Anisotropic diffusion is a popular, and theoretically well understood, technique for denoising such images. Diffusion approaches however require the selection of an "edge stopping" function, the definition of which is typically ad hoc.

3D Shape from Anisotropic Diffusion [PDF]
, 2003 We cast the problem of inferring the 3D shape of a scene from a collection of defocused images in the framework of anisotropic diffusion. We propose a novel algorithm that can estimate the shape of a scene by inferring the diffusion coefficient of a heat
