RADIAL NOISE
Noise gradients inside pixel spaces without photographic information (2019).
How do you make (a photograph) (without a camera) in space that is increasingly electronic, mathematical, and abstract?
And what remains if our precious data is lost?
“The original meaning of “noise” was “unwanted signal”; unwanted electrical fluctuations in signals received by AM radios caused audible acoustic noise (“static”). By analogy, unwanted electrical fluctuations are also called “noise”.[1] [2]
Image noise can range from almost imperceptible specks on a digital photograph taken in good light, to optical and radioastronomical images that are almost entirely noise, from which a small amount of information can be derived by sophisticated processing. Such a noise level would be unacceptable in a photograph since it would be impossible even to determine the subject.”–Wikipedia
- Various sounds, usually unwanted or unpleasant.
- He knew that it was trash day, when the garbage collectors made all the noise.
-
- Sound or signal generated by random fluctuations.
- (technology) Unwanted part of a signal. (Signal to noise ratio)
- (genetics) The measured level of variation in gene expression among cells, regardless of source, within a supposedly identical population.
- Rumour or complaint.
- The problems with the new computer system are causing a lot of noise at Head Office.
-
- A slope or incline.
- A rate of inclination or declination of a slope.
- (calculus) Of a function y = f(x) or the graph of such a function, the rate of change of y with respect to x
that is, the amount by which y changes for a certain (often unit) change in x
equivalently, the inclination to the X axis of the tangent to the curve of the graph. - (sciences) The rate at which a physical quantity increases or decreases relative to change in a given variable, especially distance.
- (mathematical analysis) A differential operator that maps each point of a scalar field to a vector pointed in the direction of the greatest rate of change of the scalar. Notation for a scalar field φ: ∇φ
- A gradual change in color. A color gradient; gradation.
