Perceptual Interpretation of Ink Annotations on Line Charts
Visualization freeform ink annotation visual perception line charts pointing deixis selection
2016/5/24
Asynchronous collaborators often use freeform ink annotations
to point to visually salient perceptual features of line
charts such as peaks or humps, valleys, rising slopes and
declining slopes. We...
Perceptual Guidelines for Creating Rectangular Treemaps
Graphical Perception Visualization Treemaps Rectangular Area Visual Encoding Experiment Mechanical Turk
2016/5/24
Treemaps are space-filling visualizations that make efficient use of limited display space to depict large amounts of hierarchical
data. Creating perceptually effective treemaps requires carefully ma...

Learning viewpoint invariant perceptual representations from cluttered images
Computational models of vision Neural Nets invariance object recognition
2015/7/31
In order to perform object recognition, it is necessary to form perceptual representations that are sufficiently specific to distinguish between objects, but that are also sufficiently flexible to gen...
SSIM-INSPIRED DIVISIVE NORMALIZATION FOR PERCEPTUAL VIDEO CODING
SSIM index rate distortion optimization residual divisive normalization H.264/AVC coding
2013/7/24
We propose a perceptual video coding framework based on anSSIM-inspired divisive normalization scheme as an attemptto transform the DCT domain frame prediction residuals toa perceptually uniform space...
A NO-REFERENCE PERCEPTUAL BLUR METRIC USING HISTOGRAM OF GRADIENT PROFILE SHARPNESS
image quality assessment blur metric gradient profile just noticeable distortion
2013/7/16
No-reference measurement of blurring artifacts in images is a challenging problem in image quality assessment field. One of the difficulties is that the inherently blurry regions in some natural image...
In this paper, a novel method for increasing the coding performance and information transmission capacity is presented. This method is mainly based on perceptual modelling of input signal such as spee...
Perceptual Scale-Space and Its Applications
Scale-space Image pyramid Primal sketch Graph grammar Generative modeling
2013/7/17
When an image is viewed at varying resolutions,it is known to create discrete perceptual jumps or transitions amid the continuous intensity changes. In this paper, we study a perceptual scale-space th...
