Representationalism, perceptual distortion and the limits of phenomenal concepts [PDF]
, 2015 This paper replies to objections from perceptual distortion against the representationalist thesis that the phenomenal characters of experiences supervene on their intentional contents.

Analysis of the Perceptual Quality Performance of Different HEVC Coding Tools
IEEE Access, 2021 Each new video encoding standard includes encoding techniques that aim to improve the performance and quality of the previous standards. During the development of these techniques, PSNR was used as the main distortion metric.

, 2012 International audienceThe rate-distortion performance of wavelet-based mesh compression algorithms is usually only evaluated in a purely geometric sense, by measures such as the Root Mean Square Error and the Hausdorff distance, which do not capture the ...

Perceptual Distortions of 3-D Finger Size [PDF]
Perception, 2019 Our body is a volumetric, three-dimensional (3-D) object in the world, and we experience it as such. Existing methods for measuring the perceptual body image, however, have been based on judgments of one-dimensional (1-D) length or two-dimensional images.

Perception-Based CTU Level Bit Allocation for Intra High Efficiency Video Coding
IEEE Access, 2019 The conventional rate control algorithm does not fully consider the characteristics of the Human Visual System (HVS). To address this problem, in this paper, a perception based Coding Tree Unit (CTU) level bit allocation algorithm for intra High ...

Zulliger R-Optimized Application in Children Victims of Sexual Violence and Cancer
Paidéia (Ribeirão Preto), 2021 Child sexual violence can cause serious damage to the psychosocial development of its victims. Assessments in this context require the use of several psychological tests with proven validity for this purpose.

Review of standard traditional distortion metrics and a need for perceptual distortion metric at a (sub) macroblock level [PDF]
, 2013 Within a video encoder the distortion metric performs an Image Quality Assessment (IQA). However, to exploit perceptual redundancy to lower the convex hull of the Rate- Distortion (R-D) curve, a Perceptual Distortion Metric (PDM) modelling of the Human ...

Perceptual distortion modeling for side-by-side 3D video delivery [PDF]
, 2014 A frame-level distortion model based on perceptual features of the human visual system is proposed to improve the performance of unequal error protection strategies and provide better quality of experience to users in Side-by-Side 3D video delivery ...

Quantifying Perceptual Distortion of Adversarial Examples
CoRR, 2019 Recent work has shown that additive threat models, which only permit the addition of bounded noise to the pixels of an image, are insufficient for fully capturing the space of imperceivable adversarial examples. For example, small rotations and spatial transformations can fool classifiers, remain imperceivable to humans, but have large additive ...

EntropyTraditional rate–distortion (RD) theory examines the trade-off between the average length of the compressed representation of a source and the additive distortions of its reconstruction.
