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...
Fusion and Perceptual Organisation of Features from Multi-sensor Data: General Concepts and New Developments
fusion interpretation recognition
2015/7/7
While the available, eventually multi-source data from remote sensing systems yield the advantage of producing more features, the
crucial point in the scene interpretation workflow is still the big, ...
DETECTION OF THE EARTHQUAKE DAMAGED BUILDINGS FROM POST-EVENT AERIAL PHOTOGRAPHS USING PERCEPTUAL GROUPING
Remote Sensing Earthquakes Detection Segmentation
2015/6/1
The collapsed buildings due to Izmit, Turkey earthquake that occurred on 17 August 1999 were detected from post-event aerial
photographs using the shadow analysis and the perceptual grouping procedu...
PERCEPTUAL ORGANIZATION OF 3D SURFACE POINTS
: Photogrammetry Vision Sciences Organization
2015/3/24
Perceptual organization is proposed as a promising intermediate process toward object recognition and reconstruction
from 3D surface points, which can be derived from aerial stereo-images, LIDAR data...

Perceptual Organization Segmentation Merging Grouping LIDAR Laser Altimetry Points 3D
2015/3/10
Perceptual organization is to group sensory primitives arising from a common underlying cause by imposing structural organization on sensory data. It has been emphasized as a robust intermediate-level...
PROBLEMS IN GEOMETRIC MODELLING AND PERCEPTUAL GROUPING OF MAN-MADE OBJECTS IN AERIAL IMAGES
Image understanding Semantics Knowledge representation Object recognition Urban objects
2014/12/31
Structural approaches of pattern recognition are frequently proposed for man-made objects in aerial images. Especially model based methods are considered using geometric, topologic and structural know...

2014/11/14
The Laboratory for Perceptual Dynamics (PDL) takes a 'complex systems' view with respect to visual awareness. In this view, ongoing internal processes in the brain prepare it for the experience of obj...
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

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...
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 the...
