Spatial context in collaborative information seeking
Journal of Information Science, 2012Space and time are considered the most important dimensions for studying systems and methods that support collaboration in information seeking. Several investigations have provided us with insights into people’s preferences and experiences relating to these two dimensions, but there is a lack of empirical evidence.

Object Tracking With Spatial Context Model
IEEE Signal Processing Letters, 2016In object tracking, building a reliable appearance model can greatly improve the performance. In this letter, we propose a novel method that uses the spatial context to help tracking based on support vector machines (SVMs). The spatial context is decomposed into different subregions that include some parts of both the target and the background.

Spatial-Temporal Context-Aware Tracking
IEEE Signal Processing Letters, 2019Discriminative correlation filters (DCFs) have recently achieved competitive performance in visual tracking benchmarks. However, most of the existing DCF trackers only consider the spatial features of the target and could hardly benefit from the inter-frame and historical information, which may degrade the tracking performance when occlusion and ...

Inferring and Distributing Spatial Context
2007An increasing number of computationally enhanced objects is distributed around us in physical space, which are equipped - or at least can be provided -- with sensors for measuring spatial contexts like position, direction and acceleration. We consider spatial relationships between them, which can basically be acquired by a pairwise comparison of their ...

Annals of the Association of American Geographers, 1974
ABSTRACT The current U.S. emphasis on geography as spatial organization has evolved over the last fifty years from an early emphasis on man-land relations followed by an emphasis on areal differentiation. The spatial view has shown both strengths and weaknesses during the sixties.

Context dependent processing in spatial hyperacuity
Vision Research, 1985The importance of comparison processes in spatial hyperacuity tasks was investigated by means of a new relative nonalignment discrimination task. Vernier-type configuations nonaligned to either left or right, were presented in succession, and the subject had to decide which configuation exhibited a larger nonalignment.

A Hierarchy of Spatial Context for Urban Computing
2012Context which consists of user experience can be described by hierarchy of time context, spatial context, social context and global context, local context, personal context. We Proposed context hierarchy for content strategy. Proposed context hierarchy takes time and spatial index and relations makes formal representation.

The Dual is the Context: Spatial Structures for GIS
2010 International Symposium on Voronoi Diagrams in Science and Engineering, 2010GIS (Geographic Information Systems) are concerned with the manipulation and analysis of spatial data at a “Geographic” scale. Apart from issues of storage, database query and visualization, they must deal with several significantly different types of spatial information.
