What is anisotropic image?

In image processing and computer vision, anisotropic diffusion, also called Perona–Malik diffusion, is a technique aiming at reducing image noise without removing significant parts of the image content, typically edges, lines or other details that are important for the interpretation of the image.

What is anisotropic diffusion filtering?

The anisotropic diffusion filter (ADF) (Perona and Malik [1990]) is a popular iterative methodology used to restore MR image intensities (Gerig et al. [1992]). By means of an edge-stopping function (ESF), this filter is capable of smoothing noisy pixels, while preserving the intensity of most edges.

What is the difference between isotropic and anisotropic diffusion?

Isotropic refers to the properties of a material which is independent of the direction whereas anisotropic is direction-dependent. These two terms are used to explain the properties of the material in basic crystallography.

What is the anisotropic effect?

The word “anisotropic” means “non-uniform”. So magnetic anisotropy means that there is a “non-uniform magnetic field”. Electrons in π systems (e.g. aromatics, alkenes, alkynes, carbonyls etc.) interact with the applied field which induces a magnetic field that causes the anisotropy.

What is anisotropy example?

An example of anisotropy is light coming through a polarizer. Another is wood, which is easier to split along its grain than across it.

What is anisotropic movement?

Anisotropy (/ˌæn. ə-, ˌæn. aɪˈsɒtr. əp. i/) is the property of a material which allows it to change or assume different properties in different directions, as opposed to isotropy.

What do you mean by anisotropic?

anisotropy, in physics, the quality of exhibiting properties with different values when measured along axes in different directions. Anisotropy is most easily observed in single crystals of solid elements or compounds, in which atoms, ions, or molecules are arranged in regular lattices.

What causes anisotropy?

The reason for natural anisotropy is the ordered arrangement of the particles in the crystals for which the separation between adjacent particles—and therefore the cohesive forces between them—varies in different directions. Anisotropy is caused by asymmetry and specific orientation of the molecules themselves.

What is anisotropic explain?

What is anisotropic effect?

Magnetic Anisotropy. The word “anisotropic” means “non-uniform”. So magnetic anisotropy means that there is a “non-uniform magnetic field”. Electrons in π systems (e.g. aromatics, alkenes, alkynes, carbonyls etc.) interact with the applied field which induces a magnetic field that causes the anisotropy.

What is anisotropic in biology?

The word anisotropic is also derived from the Greek words an means without, isos means equal and tropos means way. Thus, anisotropic meaning has different properties in different directions. It is the opposite of isotropic.
