Symbol recognition using spatial relations [PDF]

open access: yesPattern Recognition Letters, 2012
In this paper, we present a method for symbol recognition based on the spatio-structural description of a 'vocabulary' of extracted visual elementary parts. It is applied to symbols in electrical wiring diagrams. The method consists of first identifying vocabulary elements into different groups based on their types (e.g., circle, corner).

Spatial-Semantic Transformer for Spatial Relation Recognition

open access: yesJournal of Physics: Conference Series, 2023
Abstract Spatial relation recognition, which aims to predict a spatial relation predicate, has attracted increasing attention in the computer vision study. During tackling this problem, modeling spatial relation of the subjects and objects is of great importance.

Conservation of Supergravity Currents from Matrix Theory [PDF]

open access: yes, 1998
In recent work by Kabat and Taylor, certain Matrix theory quantities have been identified with the spatial moments of the supergravity stress-energy tensor, membrane current, and fivebrane current.

Point-set topological spatial relations [PDF]

open access: yesInternational journal of geographical information systems, 1991
Abstract Practical needs in geographic information systems (GIS) have led to the investigation of formal and sound methods of describing spatial relations. After an introduction to the basic ideas and notions of topology, a novel theory of topological spatial relations between sets is developed in which the relations are defined in terms of the ...

Optimization Beyond the Convolution: Generalizing Spatial Relations with End-to-End Metric Learning

open access: yes, 2019
To operate intelligently in domestic environments, robots require the ability to understand arbitrary spatial relations between objects and to generalize them to objects of varying sizes and shapes. In this work, we present a novel end-to-end approach to

A Comparative Study of Descriptors for Quadrant-Convexity

open access: yesMathematics
Many different descriptors have been proposed to measure the convexity of digital shapes. Most of these are based on the definition of continuous convexity and exhibit both advantages and drawbacks when applied in the digital domain.

SPATIAL PICTURE OF THE WORLD IN DIFFERENT LANGUAGES AND CULTURES

open access: yesSovremennye Issledovaniâ Socialʹnyh Problem, 2022
The article is devoted to the study of the spatial picture of the world in various languages and cultures. The culturally determined differences in the categorization of space and spatial relations in different languages are considered, the ways of ...

The Spatial Relations of Genes [PDF]

open access: yesProceedings of the National Academy of Sciences, 1919
Castle(1) has proposed an arrangement of linked genes in three dimensions, based on the assumption that the distance between any two loci is exactly proportional to the observed crossover value. He believes that this system gives a better agreement between observation and expectation than does the hypothesis of a strictly linear arrangement that we ...

What spatial environments mean

open access: yesJournal of Spatial Information Science, 2020
Language is one of the most prominent means of representing human thought. Spatial cognition research has made use of this fact for decades, exploring how humans perceive and understand their spatial environments through language analysis.
