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 کاملA 3D Perceptual Metric using Just-Noticeable-Difference
In multimedia applications, it is essential to distribute resources efficiently among different types of data in order to optimize overall quality. We propose a perceptual metric using Just-Noticeable-Difference (JND) to identify redundant mesh data so that available bandwidth can be allocated to improve texture resolution. Evaluation of perceptual impact during runtime is based on statistics i...

متن کاملPsychophysics and Just - Noticeable Difference CMSC 828 D Report
The study of psychophysics seeks to explore and quantify the relationships between intensities of physical stimuli and one’s perceptions of those stimuli. Rooted in Ernst Weber’s early investigations into the minimum change in intensity necessary to affect a noticeable difference in sensation (known as “just-noticeable difference,” or JND), psychophysics and its methods provide the foundations ...
متن کاملThe Just-Noticeable Difference in Speech-to-Noise Ratio
Just-noticeable differences (JNDs) have been measured for various features of sounds, but despite its importance to communication, there is no benchmark for what is a just-noticeable-and possibly meaningful-difference in speech-to-noise ratio (SNR). SNR plays a crucial role in speech communication for normal-hearing and hearing-impaired listeners. Difficulty hearing speech in background noise-a...
