The automatic extraction of spatial information is a challenging and novel task with many applications. We motivate our definition of this task and formulate it as an information extraction step prior to mapping to spatial semantics. Each sentence gives rise to several spatial relations between words representing landmarks, trajectors and spatial indicators. Learning to extract such spatial rel...

The aim of this paper is to propose a robot referee for robot soccer. This idea is implemented using a service robot that moves along one of the field sides, uses its own cameras to analyze the game, and communicates its decisions to the human spectators using speech, and to the robot players using wireless communication. The robot uses a video-based game analysis toolbox that is able to analyz...

This paper presents an approach to vision-based mobile robot localization. In an attempt to capitalize on the benefits of both image and landmark-based methods, we describe a method that combines their strengths. Images are encoded as a set of visual features called landmarks. Potential landmarks are detected using an attention mechanism implemented as a measure of uniqueness. They are then sel...

Repeatability of traditional kinematic and kinetic models is affected by the ability to accurately locate anatomical landmarks (ALs) to define joint centres and anatomical coordinate systems. Numerical methods that define joint centres and axes of rotation independent of ALs may also improve the repeatability of kinematic and kinetic data. The purpose of this paper was to compare the repeatabil...

HARP-images of each harmonic peak. The phase is distorted due to B0-inhomogeneity, e.g. in the liver. d) (=b+c) B0-map. e) (=bd/2) Peak-combined HARP-image: Phase wraps of B0-map are present, impairing HARP-analysis. f) Unwrapped B0-map. g) (=b-f/2) Peak-combined HARP-image: No phase distortions (wraps aligned with taglines) and no phase-wraps from B0-map. h) Fully unwrapped peak-combined HARPi...

The paper generalises the notion of landmarks for reasoning about planning problems involving propositional and numeric variables. Intuitively, numeric landmarks are regions in the metric space defined by the problem whose crossing is necessary for its resolution. The paper proposes a relaxationbased method for their automated extraction directly from the problem structure, and shows how to exp...

The idea of a presidential address seems to require a lecture delivered in the most refined and dignified scientific atmosphere yet understandable to the layman, a lecture which treats a difficult field of mathematics in such a complete manner that the audience has the excitement, the aesthetic enjoyment of seeing a mystery resolved, perhaps only with the slightly bitter feeling, of asking afte...

Dependence on landmark points or high-order derivatives when establishing correspondences between geometrical image curves under various subclasses of projective transformation remains a shortcoming of present methods. In the proposed framework, geometric transformations are treated as smooth functions involving the parameters of the curves on which the transformation basis points lie. By allow...

OBJECTIVES To compare the landmark-guided technique versus the ultrasound-guided technique for internal jugular vein cannulation in spontaneously breathing patients. METHODS A total of 380 patients who required internal jugular vein cannulation were randomly assigned to receive internal jugular vein cannulation using either the landmark- or ultrasound-guided technique in Bursa, Uludag Univers...

Allocentric spatial memory was studied in dogs of varying ages and sources using a landmark discrimination task. The primary goal of this study was to develop a protocol to test landmark discrimination learning in the dog. Using a modified version of a landmark test developed for use in monkeys, we successfully trained dogs to make a spatial discrimination on the basis of the position of a visu...
