Episodic memory for spatial context biases spatial attention
Experimental Brain Research, 2008The study explores the bottom-up attentional consequences of episodic memory retrieval. Individuals studied words (Experiment 1) or pictures (Experiment 2) presented on the left or on the right of the screen. They then viewed studied and new stimuli in the centre of the screen.

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.

Randomized Spatial Context for Object Search
IEEE Transactions on Image Processing, 2015Searching visual objects in large image or video data sets is a challenging problem, because it requires efficient matching and accurate localization of query objects that often occupy a small part of an image. Although spatial context has been shown to help produce more reliable detection than methods that match local features individually, how to ...

Spatial Context-Aware Recommendation
2016As a user can only visit a limited number of venues/events and most of them are within a limited distance range, the user-item matrix is very sparse, which creates a big challenge for traditional collaborative filtering-based recommender systems. The problem becomes more challenging when people travel to a new city where they have no activity history ...

High-Order Local Spatial Context Modeling by Spatialized Random Forest
IEEE Transactions on Image Processing, 2013In this paper, we propose a novel method for spatial context modeling toward boosting visual discriminating power. We are particularly interested in how to model high-order local spatial contexts instead of the intensively studied second-order spatial contexts, i.e., co-occurrence relations.

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 ...

Spatial Embedding and Spatial Context
2009A serious issue in urban 2D remote sensing is that even if you can identify linear features it is often difficult to combine these to form the object you want - the building. The classical example is of trees overhanging walls and roofs: it is often difficult to join the linear pieces together.

IMAGE RETRIEVAL USING SPATIAL CONTEXT
Recent Trends in Multimedia Information Processing, 2002Abstract This paper presents an image retrieval system based on modelling the spatial relationship between image contents. We model the relationship between image objects to help image retrieval. This approach first detects objects and determines their label in an image and then codes their Spatial relationship using binary patterns. Image retrieval is

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.

Externalities in a spatial context
Journal of Public Economics, 1977Abstract In this paper air pollution externalities are analyzed in an explicit spatial setting that recognizes the spatial interdependence of polluters and their victims. Optimal environmental policies are shown to consist not only of Pigouvian taxes but of two other policies.
