Filtration

Science / Biology / Filtration: The removal of water and solutes from the blood; occurs in the glomerulus of the nephron.

Low-Pass Filtration

Science / Spiders / Low-Pass Filtration: multiplication of the Fourier transform of an image with a 2D function ('the filter') that attenuates amplitudes at high spatial frequencies k. This has the result of blurring the image, and of elimin MORE

Infiltration

Business / Agriculture / Infiltration: The downward entry of water into soil. Also called percolation. A high rate of infiltration means that soil moisture for crops will be higher. Many conservation practices, such as conservation tillage MORE

Neutral Filtration

Entertainment / Photography / Neutral Filtration: In color printing is the filtration at which color balance is achieved, rendering a neutral gray ion the film image as a neutral gray on the photographic paper. MORE

Wiener Filtration

Science / Spiders / Wiener Filtration: application of the Wiener filter, designed to restore a signal in the presence of noise in an optimal way, in the least-square sense. MORE

High-Pass Filtration

Science / Spiders / High-Pass Filtration: multiplication of the Fourier transform of an image with a rotationally symmetric 2D function ('the filter') that attenuates amplitudes at low spatial frequencies k and increases amplitudes for high s MORE

Debourbage

Life Style / Wine / Debourbage: Refers to a process in which the must of a white wine is allowed to settle before racking off the wine, this process reduces the need for filtration or fining. MORE
