Visual graph modeling for scene recognition and mobile robot localization

TL;DR: Experimental results show that using visual graph model (VGM) improves the accuracies of the results of the standard language model (LM) and outperforms the Support Vector Machine (SVM) method.
Journal ArticleDOI

Deriving topological relations between regions from direction relations

TL;DR: The methods can provide topological information when topological relations are unavailable, or more precise results are expected, and are helpful in the integration of the calculi for topological and direction relations.

Reactive Navigation in Partially Familiar Planar Environments Using Semantic Perceptual Feedback

TL;DR: This article solves the planar navigation problem by recourse to an online reactive scheme that exploits recent advances in simultaneous localization and mapping (SLAM) and visual object recognition to recast prior geometric knowledge in terms of an offline catalog of familiar objects.
Journal ArticleDOI

An Unified CGA-Based Formal Expression of Spatio-Temporal Topological Relations for Computation and Analysis of Geographic Objects

TL;DR: The research provides theoretical and methodological support for expressing and computing the spatio-temporal topological relations among any set of geographic objects and enhances the analytical capabilities of GIS for dealing with both space and time.

Medical Image Segmentation Using Multi-level Set Partitioning with Topological Graph Prior

TL;DR: This novel method is capable of segmenting adjacent objects with very close gray level that would be difficult to segment correctly using standard methods, and shows the graph prior technique to explain how it gives precise multi-region segmentation.

Metaphors We Live By

TL;DR: Lakoff and Johnson as mentioned in this paper suggest that these basic metaphors not only affect the way we communicate ideas, but actually structure our perceptions and understandings from the beginning, and they offer an intriguing and surprising guide to some of the most common metaphors and what they can tell us about the human mind.

Metaphors We Live by

TL;DR: Lakoff and Johnson as discussed by the authors present a very attractive book for linguists to read, which is written in a direct and accessible style; while it introduces and uses a number of new terms, for the most part it is free of jargon.

Maintaining knowledge about temporal intervals

James F. Allen
- 01 Mar 1991 - 
TL;DR: An interval-based temporal logic is introduced, together with a computationally effective reasoning algorithm based on constraint propagation, which is notable in offering a delicate balance between space and time.

The Theory of Parsing, Translation, and Compiling

TL;DR: It is the hope that the algorithms and concepts presented in this book will survive the next generation of computers and programming languages, and that at least some of them will be applicable to fields other than compiler writing.
