In the theory of perception, he argued that perceptual errors and hallucinations can be explained by various properties being present in a manner other than exemplification. en.wikipedia.org Thus, cognitive biases may sometimes lead to perceptual distortion, inaccurate judgment, illogical interpretation,...
The audible error surface must be interpreted to produce an estimate of the overall subjective judgement which would result from the particular distortion. Ideally, the interpretation of the error surface should be broadly analogous to human perceptual mechanisms, and equally, it would be desirable to...
Testing was conducted in accordance with the Koppitz procedure, but errors of distortion, rotation, integration, and preservation were determined separately. The total time required to reproduce the designs were also recorded. The reliability estimate for the Koppitz score was generally satisfactory, but...
In Section 5.05.4 several practical examples of use of HVS sensitivity models in the design of perceptual coding tools will be presented and discussed. In this chapter, the sensitivity to coding artifacts is quantified by means of the Just Noticeable Distortion (JND) concept. JND refers to the...
A perceptual quality based rate distortion model Rate and distortion models (R-D models) are important for current image/video encoders. They can help encoders to find the best encoding parameters for imp... W Chao,X Mou,Z Lei - Fourth International Workshop on Quality of Multimedia Experien...
Effects of group pressure on modification and distortion of judgments Individuals were placed in experimentally structured groups in which they found themselves consistently contradicted by the other "members" of the group in simple perceptual judgments. This investigation of the minority of one in the ...
However, a hitherto untested prediction is that, due to reduced divisive normalization, the “distortion” of orientation perception by context (the added grating) is less pronounced or absent in ASD. This prediction is tested in the present study. Results 11 young adults with ASD and 12 age-...
One way to analyze how information pertaining to distortion can be conveyed to viewers is through their mechanisms of perception. The resulting axis is a cultural axis in that the distinctions between viewing cues are made primarily by which communities within society might be expected to be familia...
In fact there may be errors in perception. The image falls directly onto to the retina which is later processed and interpreted by the brain. The interpretations may not necessarily be always correct and this misinterpretation of information which is perceived by our sensory receptors is called as...
viewers of watermarked images do not have access to the originals. Thus, for those watermarking applications, quality is more important than fidelity. In order tomeasure qualityor fidelity one needs to quantify the degree of distortion introduced to an image due to watermarking and, if possible, ...
