just noticeable difference , jnd (skrót)

A good metric should take this into account in order for the notion of a "just noticeable difference" to have meaning.

The predicted just noticeable difference was comparable to that achieved by humans in behavioral tests.

However, as the number of intervals increases it becomes harder to distinguish the notes from each other (see just noticeable difference).

Yet when the speed differential crosses a certain threshold, say 6 mph, you notice it-what Weber called a "just noticeable difference."

The contour of the ellipse therefore represents the just noticeable differences of chromaticity.

MacAdam ellipse, the region of chromaticity representing just noticeable differences to the human eye.

Weber found that the just noticeable difference (jnd) between two weights was approximately proportional to the weights.

Weber fractions enumerate the phenomenon, and lower Weber fractions indicate lower "just noticeable differences."

Rand Evans, "The Just Noticeable Difference: Psychophysical instrumentation and the determination of sensory thresholds".

The contacts that are high in either Information or Attractive Value, or both, is then rank-ordered by their importance using the "Just Noticeable Difference" system.

Different studies have proposed different ΔE values that have a JND (just noticeable difference).

It was found that this distance (JND, Just Noticeable Difference) decreases dramatically with practice, and that this improvement is at least partially retained on subsequent days.

In academic studies of color blindness, on the other hand, there is more interest in developing flexible tests to collect thorough datasets, identify copunctal points, and measure just noticeable differences.

We take a little trip through lighthouses, the education of orphans, psycho-physics, the law of the just noticeable difference, which is the idea behind stellar magnitudes, which leads us to discovering the size of the universe.

Tinted fields highlight differences greater than 5 cents (1/20th of a semitone), which is the human ear's "just noticeable difference" for notes played one after the other (smaller differences are noticeable with notes played simultaneously).

In psychophysical terms, the size difference between A and C is above the just noticeable difference ('jnd') while the size differences between A and B and B and C are below the jnd.

The BEF format can archive image data with any dynamic range, full human color range, and a quality setting directly tied to color data precision (the used techniques ties it with JND - just noticeable difference parameter).

Sufficient differences in frequency give rise to a difference in perceived hue; the just noticeable difference in wavelength varies from about 1 nm in the blue-green and yellow wavelengths, to 10 nm and more in the red and blue.

The use of the term mired dates back to Irwin G. Priest's observation in 1932 that the just noticeable difference between two illuminants is based on the difference of the reciprocals of their temperatures, rather than the difference in the temperatures themselves.

At low speeds countersteering is equally necessary, but the countersteering is then so subtle that it is hidden by the continuous corrections that are made in balancing the bike, often falling below a just noticeable difference or threshold of perception of the rider.

The threshold of what is perceptible, technically known as the just noticeable difference, also varies as a function of the timbre of the pitch: in one study, changes in tone quality reduced student musicians' ability to recognize as out-of-tune pitches that deviated from their appropriate values by 12 cents.

In terms of Thurstone's conceptual framework, the association posited between perceived stimulus intensity and the physical magnitude of the stimulus in the Weber-Fechner law will only hold when Weber's law holds and the just noticeable difference (JND) is treated as a unit of measurement.
