2. 1. Visual Attention in Active Vision Systems : Attending, Classifying and Manipulating Objects

   Author : Babak Rasolzadeh; Jan-Olof Eklundh; Ales Leonardis; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; visual attention; saliency map; compter vision; robotics; active vision; machine learning;

   Abstract : This thesis has presented a computational model for the combination of bottom-up and top-down attentional mechanisms. Furthermore, the use for this model has been demonstrated in a variety of applications of machine and robotic vision. READ MORE

4. 2. Stereoscopic Label Placement : Reducing Distraction and Ambiguity in Visually Cluttered Displays

   Author : Stephen D. Peterson; Anders Ynnerman; Matthew Cooper; John Wann; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Label placement; user interfaces; stereoscopic displays; augmented reality; virtual reality; visual clutter; Computer science; Datavetenskap;

   Abstract : With increasing information density and complexity, computer displays may become visually cluttered, adversely affecting overall usability. Text labels can significantly add to visual clutter in graphical user interfaces, but are generally kept legible through specific label placement algorithms that seek visual separation of labels and other objects in the 2D view plane.

5. 3. Visualizing Cluster Patterns at Scale : A Model and a Library

   Author : Elio Ventocilla; Maria Riveiro; Göran Falkman; Rafael M. Martins; Katerina Vrostou; Högskolan i Skövde; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Visual analytics; cluster patterns; big data; unsupervised learning; multidimensional projections; vector quantization; progressive visual analytics; Skövde Artificial Intelligence Lab SAIL ; Skövde Artificial Intelligence Lab SAIL ;

   Abstract : Large quantities of data are being collected and analyzed by companies and institutions, with the aim of extracting knowledge and value. When little is known about the data at hand, analysts engage in exploratory data analysis to achieve a better understanding. READ MORE

6. 4. Robust Visual Object Tracking mean shift, particle filters and point features

   Author : Zulfiqar Hasan Khan; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PF; MSEPF; mean shift; visual object tracking; RANSAC; SIFT; SURF;

   Abstract : Visual object tracking has been identified as a promising technique for many computer vision applications like surveillance, flight navigation, video compression and driver assistance. The main idea is to find the state ofthe object and how it changes over time, in recursive video frames. READ MORE

7. 5. Visual Analysis of Multidimensional Data for Biomechanics and HCI

   Author : Gregorio Palmas; Tino Weinkauf; Silvia Miksch; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datalogi;

   Abstract : Multidimensional analysis is performed in many scientific fields.Its main tasks involve the identification of correlations between data dimensions,the investigation of data clusters, and the identification of outliers. Visualization techniques often help in getting a better understanding. READ MORE
