21. Artificial intelligence in PET-CT. From Image Enhancement to Imaging Biomarkers
Sammanfattning : .... LÄS MER
22. Novel Layered and 2D Materials for Functionality Enhancement of Contacts and Gas Sensors
Sammanfattning : Chemical gas sensors are widely-used electronic devices for detecting or measuring the density levels of desired gas species. In this study, materials with established or potential applications for gas sensors are treated. LÄS MER
23. Improving image quality in multi-channel printing - multilevel halftoning, color separation and graininess characterization
Sammanfattning : Color printing is traditionally achieved by separating an input image into four channels (CMYK) and binarizing them using halftoning algorithms, in order to designate the locations of ink droplet placement. Multi-channel printing means a reproduction that employs additional inks other than these four in order to augment the color gamut (scope of reproducible colors) and reduce undesirable ink droplet visibility, so-called graininess.

24. Local symmetry features in image processing
Sammanfattning : The extraction of features is necessary for all aspects of image processing and analysis such as classification, segmentation, enhancement and coding. In the course of developing models to describe images, a need arises for description of more complex structures than lines. LÄS MER
25. Taming the Griffin : Membrane interactions of peripheral and monotopic glycosyltransferases and dynamics of bacterial and plant lipids in bicelles
Sammanfattning : Biological membranes form a protective barrier around cells and cellular compartments. A broad range of biochemical processes occur in or at membranes demonstrating that they are not only of structural but also of functional importance. One important class of membrane proteins are membrane-associated glycosyltransferases. LÄS MER
