2. 1. Contributions to 3D Image Analysis using Discrete Methods and Fuzzy Techniques : With Focus on Images from Cryo-Electron Tomography

   Author : Magnus Gedda; Ewert Bengtsson; Stina Svensson; Carolina Wählby; Punam Saha; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; digital image analysis; 3D; fuzzy; algorithms; grey-weighted distance; region growing; electron tomography; tracing; fluorescence microscopy; Datoriserad bildanalys; Computerized Image Analysis;

   Abstract : With the emergence of new imaging techniques, researchers are always eager to push the boundaries by examining objects either smaller or further away than what was previously possible. The development of image analysis techniques has greatly helped to introduce objectivity and coherence in measurements and decision making. READ MORE

4. 2. Synthesis, Coding, and Evaluation of 3D Images Based on Integral Imaging

   Author : Roger Olsson; Youzhi Xu; Mårten Sjöström; Tingting Zhang; Aljoscha Smolic; Mittuniversitetet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integral Imaging; 3D images; coding; quality evaluation; H.264 AVC; JP3D; Telecommunication; Telekommunikation;

   Abstract : In recent years camera prototypes based on Integral Imaging (II) have emerged that are capable of capturing three-dimensional (3D) images. When being viewed on a 3D display, these II-pictures convey depth and content that realistically change perspective as the viewer changes the viewing position. READ MORE

5. 3. 3D Electron crystallography : Real space reconstruction and reciprocal space tomography

   Author : Daliang Zhang; Xiaodong Zou; Douglas L. Dorset; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electron crystallography; Electron microscopy; Porous materials; Chemistry; Kemi; Structural Chemistry; strukturkemi;

   Abstract : Electron crystallography is an important technique for studying micro- and nano-sized materials. It has two important advantages over X-ray crystallography for structural studies: 1) crystals millions of times smaller than those needed for X-ray diffraction can be studied; 2) it is possible to; focus the electrons to form an image.

6. 4. CT with 3D-Image Reconstructions in Preoperative Planning

   Author : Angeliki Dimopoulou; Anders Magnusson; Anders Persson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CT Angiography; 3D-image reconstructions; haemodialysis; AVF AVG; DIEP flap; surgery time; complicated renal calculi; PNL; true nonenhanced images; virtual nonenhanced images; CT Urography; Radiology; Radiologi;

   Abstract : Computed tomography is one of the most evolving fields of modern radiology. The current CT applications permit among other things angiography, 3D image reconstructions, material decomposition and tissue characterization. CT is an important tool in the assessment of specific patient populations prior to an invasive or surgical procedure. READ MORE

7. 5. Visualizing Dynamics –The Perception of Spatiotemporal Data in 2D and 3D

   Author : Andreas Kjellin; Mats Lind; Else Nygren; Kjell Ohlsson; Uppsala universitet; []
   Keywords : Människa-dator-interaktion; Human-Computer Interaction; Information Visualization; Usability; 2D; 3D; Cue Probability Learning; Space-time Cub; Människa-dator-interaktion;

   Abstract : In many command and control situations the understanding of dynamic events is crucial. With today’s development of hard- and software architecture, we have the possibility to visualize data in two-dimensional (2D) and three-dimensional (3D) images. READ MORE
