ShapeFit and ShapeKick for Robust, Scalable Structure from Motion
We introduce a new method for location recovery from pair-wise directions
that leverages an efficient convex program that comes with exact recovery
guarantees, even in the presence of adversarial outliers. When pairwise
directions represent scaled relative positions between pairs of views
(estimated for instance with epipolar geometry) our method can be used for
location recovery, that is the determination of relative pose up to a single
unknown scale. For this task, our method yields performance comparable to the
state-of-the-art with an order of magnitude speed-up. Our proposed numerical
framework is flexible in that it accommodates other approaches to location
recovery and can be used to speed up other methods. These properties are
demonstrated by extensively testing against state-of-the-art methods for
location recovery on 13 large, irregular collections of images of real scenes
in addition to simulated data with ground truth
Straight-line Drawability of a Planar Graph Plus an Edge
We investigate straight-line drawings of topological graphs that consist of a
planar graph plus one edge, also called almost-planar graphs. We present a
characterization of such graphs that admit a straight-line drawing. The
characterization enables a linear-time testing algorithm to determine whether
an almost-planar graph admits a straight-line drawing, and a linear-time
drawing algorithm that constructs such a drawing, if it exists. We also show
that some almost-planar graphs require exponential area for a straight-line
drawing
Health and health behaviours among a cohort of first year nursing students in Scotland: A self-report survey
The study aim was to collect data on the health and health-related behaviours of undergraduate nursing students at a Higher Education Institution in Scotland, to identify the need for potential health behaviour change interventions as part of their undergraduate course. An anonymous self-report questionnaire (with questions about physical activity, diet, sleep, alcohol, smoking, mental health) was administered to first year nursing students at a Scottish university. The response rate was 88%, with 207 respondents (26 male, 178 female, 3 other). Age ranged from 16 to 45 years (mean 24.5 years). Overall, 48 (23.1%) students rated their physical health as excellent/very good, and 100 (48.3%) their mental health as such. 157 (76.2%) students were achieving 150 min of physical activity per week. There were 48 (29%) and 30 (18.2%) overweight and obese students respectively. 129 (62.6%) students viewed a mobile device for > 30 min before sleep. 176 (86.3%) students consumed alcohol, with 32 (15.4%) reporting binge drinking. The prevalence of current smoking was 24.8%. The students’ health behaviour profile was therefore broadly similar to that of the general population in Scotland, but smoking, diet, sleep practices and binge-drinking were identified as priority areas for health education and intervention
Octilinear Force-Directed Layout with Mental Map Preservation for Schematic Diagrams
We present an algorithm for automatically laying out metro map style schematics using a force-directed approach, where we use a localized version of the standard spring embedder forces combined with an octilinear magnetic force. The two types of forces used during layout are naturally conflicting, and the existing method of simply combining these to generate a resultant force does not give satisfactory results. Hence we vary the forces, emphasizing the standard forces in the beginning to produce a well distributed graph, with the octilinear forces
becoming prevalent at the end of the layout, to ensure that the key requirement of line angles at intervals of 45? is obtained. Our method is considerably faster than the more commonly used search-based approaches, and we believe the results are superior to the previous force-directed approach. We have further developed this technique to address the issues of dynamic schematic layout. We use a Delaunay triangulation to construct a schematic “frame”, which is used to retain relative node positions and permits full control of the level of mental map preservation.
This technique is the first to combine mental map preservation techniques with the additional layout criteria of schematic diagrams. To conclude, we present the results of a study to investigate the relationship between the level of mental map preservation and the user response time and accuracy
