Generating Personalized Spatial Analogies for Distances and Areas
Distance area landmark locator map spatial analogy information visualization
2016/5/24
Distances and areas frequently appear in text articles. However,
people struggle to understand these measurements when
they cannot relate them to measurements of locations that
they are personally ...
Social and Spatial Patterns of Cultural Heritage
digital analysis field survey spatial infrastructure traditional settlements
2015/11/13
This paper is concerned with the ways in which traditional settlements are studied and analyzed in order to facilitate knowledge, interpretation and consequently presentation and preservation of cultu...
Visual Conspicuity Index: Spatial Dissimilarity, Distance, and Central Bias
central bias conspicuity dissimilarity spatial distance visual saliency
2013/7/24
We propose an image conspicuity index that combines three factors: spatial dissimilarity, spatial distance andentral bias. The dissimilarity between image patches is evaluatedin a reduced dimensional ...
SIDE INFORMATION EXTRAPOLATION WITH TEMPORAL AND SPATIAL CONSISTENCY
Distributed video coding side information extrapolation temporal and spatial consistency regularized local linear regression
2013/7/24
In this paper, we present an efficient side information extrapolation scheme with temporal and spatial consistency for lowdelay Wyner-Ziv videocoding. Our method is based on theregularized local...
Attention Driven Face Recognition: A Combination of Spatial Variant Fixations and Glance
Face Recognition Human Visual System
2013/7/24
This paper proposes a novel face recognitionalgorithm inspired by the selective attention of Human VisualSystem (HVS). We record four observers’ eye movements whenthey are viewing 100 FRGC [1] frontal...
Advanced Spatial and Temporal Direct Mode for B Picture Coding
Advanced Spatial Temporal Direct Mode
2013/7/24
The direct mode in H.264/AVC can efficiently improve the coding performance of B pictures, since it exploits the spatial or temporal correlation by deriving its motion vector from previously encoded i...

We propose an image conspicuity index that combines three factors: spatial dissimilarity, spatial distance andcentral bias. The dissimilarity between image patches is evaluatedin a reduced dimensional...
Modeling spatial and semantic cues for large-scale near-duplicated image retrieval
And–Or graph face fusion gender conversion
2013/7/24
Bag-of-visual Words (BoW) image representation has been illustrated as one of the most promising solutions for large-scale near-duplicatedimageretrieval. However, the traditional visual vocabulary is ...
Image Quality Assessment Using Spatial Frequency Component
Image quality assessment low spatial component high spatial component HVS
2013/7/16
Image quality assessment (IQA) is a crucial technique in perceptual image/video coding, because it is not only a ruler for performance evaluation of coding algorithms but also a metric for ratio-disto...
SPATIAL-TEMPORAL VIDEO BROWSING FOR MOBILE ENVIRONMENT BASED ON VISUAL ATTENTION ANALYSIS
visual attention spatial-temporal summary mobile environment
2013/7/16
In this paper, we propose an attention based method to provide convenient browsing experience on mobile devices. To achieve this, we extract video summary in both temporal and spatial domains. Firstly...
SPATIAL-TEMPORAL NONPARAMETRIC BACKGROUND SUBTRACTION IN DYNAMIC SCENES
Background modeling moving objects detection Gaussian mixture model kernel density estimation
2013/7/16
Traditional background subtraction methods model only temporal variation of each pixel. However, there is also spatial variation in real word due to dynamic background such as waving trees, spouting f...
Spatial-Aided Low-Delay Wyner-Ziv Video Coding
Spatial-Aided Low-Delay Wyner-Ziv Video Coding
2013/7/16
In distributed video coding, the side information (SI) quality plays an important role in Wyner-Ziv (WZ) frame coding. Usually,SI is generated at the decoder by the motion-compensated interpolation (M...
