The derivation of subjective scales from just noticeable differences.
The study of cumulated jnd scales began with Fechner; Fechner's law is such a scale. Psychophysicists have been deriving such scales and comparing them with scales derived in other ways, notably by fractionation, ever since, and a lot of controversy has resulted. The controversy is particularly hot at present because Stevens and Galanter (16) and Stevens (14) have assembled a lot of data which ...
متن کاملJust Noticeable Difference Estimation Using Visual Saliency in Images
Due to some physiological and physical limitations in the brain and the eye, the human visual system (HVS) is unable to perceive some changes in the visual signal whose range is lower than a certain threshold so-called just-noticeable distortion (JND) threshold. Visual attention (VA) provides a mechanism for selection of particular aspects of a visual scene so as to reduce the computational loa...
متن کاملImproved estimation for just-noticeable visual distortion
Perceptual visibility threshold estimation, based upon characteristics of the human visual system (HVS), has wide applications in digital image/video processing. An improved scheme for estimating just-noticeable distortion (JND) is proposed in this paper. It is proved to outperform the DCTune model, with the major contributions of a new formula for luminance adaptation adjustment and the incorp...
متن کاملJust noticeable differences in component concentrations modify the odor quality of a blending mixture.
The odors we perceive are mainly the result of mixtures of odorants that, however, are commonly perceived as single undivided entities; nevertheless, the processes involved remain poorly explored. It has been recently reported that perceptual blending based on configural olfactory processing can cause odorant mixtures to give rise to an emergent odor not present in the components. The present s...
متن کاملJust noticeable differences of open quotient and asymmetry coefficient in singing voice.
This study aims to explore the perceptual relevance of the variations of glottal flow parameters and to what extent a small variation can be detected. Just Noticeable Differences (JNDs) have been measured for three values of open quotient (0.4, 0.6, and 0.8) and two values of asymmetry coefficient (2/3 and 0.8), and the effect of changes of vowel, pitch, vibrato, and amplitude parameters has be...
