data visualization is the process of transforming data, information, and knowledge into visual form, making use of humans’ natural visual capabilities which reveals relationships in data sets that are not evident from the raw data, by using mathematical techniques to reduce the number of dimensions in the data set while preserving the relevant inherent properties. in this paper, we formulated d...

Electrophysiology procedures are in many cases performed under fluoroscopic guidance. As the heart is not visible under fluoroscopy, a preoperatively acquired heart model of the patient may be fused with the live X-ray images to provide the physician with a better orientation. This heart model needs to be registered to the fluoroscopic images. Currently, registration is performed manually, e.g....

Human action recognition based on skeletons has wide applications in human–computer interaction and intelligent surveillance. However, view variations and noisy data bring challenges to this task. What’s more, it remains a problem to effectively represent spatio-temporal skeleton sequences. To solve these problems in one goal, this work presents an enhanced skeleton visualization method for vie...

This study presents a novel version of the Visualization Induced Self-Organizing Map based on the application of a new fusion algorithm for summarizing the results of an ensemble of topology preserving mapping models. This algorithm is referred to as Weighted Voting Superposition (WeVoS). Its main feature is the preservation of the topology of the map, in order to obtain the most truthful visua...

Indoor environments are challenging spaces to handle in location analysis and Geographic Information Science. In this paper, new techniques to visualize solutions of location models used for the optimal indoor placement of emergency devices are proposed in support of location planning decisions. The analysis compares and contrasts extensions of traditional 2D visualization techniques to display...

UNLABELLED High-throughput genotyping and sequencing technologies facilitate studies of complex genetic traits and provide new research opportunities. The increasing popularity of genome-wide association studies (GWAS) leads to the discovery of new associated loci and a better understanding of the genetic architecture underlying not only diseases, but also other monogenic and complex phenotypes...

CID map (similar results obtained for CIR and inclination maps) obtainable in as little as one minute following CA injection, compared to (b) T2w and (c) SSFP imaging that visualize a more homogeneous lesion. (d) Delayed enhancement imaging acquired many minutes post-contrast injection demonstrate similar lesion core and border regions after subtraction with pre-contrast data. a b c d VISUALIZA...

While technology matures and becomes more productive, mobile devices can be affordable and, consequently, fully integrated in people’s lives. After their unexpected bloom and acceptance, Online Social Networks are now sources of valuable information. The authors therefore use them for tasks varying from direct marketing to forensic analysis. The authors have already seen Social Network Forensic...

We present a physically based method for visualizing deformation in particle simulations, such as those describing structural mechanics simulations. The method uses the deformation gradient tensor to transform carefully chosen glyphs representing each particle. The visualization approximates how simulated objects responding to applied forces might look in reality, allowing for a better understa...
