Just noticeable difference
Jnd: just noticeable difference in the field of psychophysics, that branch of experimental psychology that studies sensation and perception, a jnd is the amount that something must be changed for the difference to be noticeable, defined to mean that the change is detectable half the time. The concept of just noticeable difference (jnd), also known as the difference threshold or difference limen (latin for threshold), derives from early work in the area of classical psychophysics conducted in the mid-nineteenth century. Weber’s law states that the size of the just noticeable difference (jnd) is a constant proportion(k times) of the original stimulus value it is the minimum amount by which.

The award citation was for their many contributions to the objective assessment and prediction of display image quality, including the development of the first display-quality metric quantified in perceptual units of just-noticeable differences (jnds. A useful general reference is that the just noticeable difference in sound intensity for the human ear is about 1 decibel jnd = 1 decibel in fact, the use of the factor of 10 in the definition of the decibel is to create a unit which is about the least detectable change in. In psychophysics, a just noticeable difference, customarily abbreviated with lowercase letters as jnd, is the smallest difference in a specified modality of sensory input that is detectable by a human being or other animal it is also known as the difference limen or the differential threshold.

The differential threshold or just noticeable difference (jnd) is defined by schiffman et al (2013) as ‘the minimal difference that can be detected between two stimuli’ weber’s law states that the jnd between two stimuli is relative to the intensity of the first stimulus. Just noticeable difference in the branch of experimental psychology focused on sense, sensation, and perception, which is called psychophysics, a just-noticeable difference or jnd is the amount something must be changed in order for a difference to be noticeable, detectable at least half the time (absolute threshold.
