Just 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 کاملThe 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 کاملSpatio-temporal Just Noticeable Distortion Model Guided Video Watermarking
Perceptual Watermarking should take full advantage of the results from human visual system (HVS) studies. Just noticeable distortion (JND), which refers to the maximum distortion that the HVS does not perceive, gives a way to model the HVS accurately. An effective Spatio-Temporal JND model guided video watermarking scheme in DCT domain is proposed in this paper. The watermarking scheme is based...
