1. Quality enhancement of time-resolved computed tomography scans with cycleGAN
University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenAbstract : Time-resolved x-ray tomography enables us to dynamically and non-destructively study the interior of a specimen. The obtainable temporal resolution is limited by the x-ray flux and the desired spatial resolution. READ MORE

2. Investigating magnetic reconnectionevents in the solar chromosphere
University essay from Stockholms universitet/Institutionen för astronomiAbstract : The focus of this thesis is to investigate magnetic reconnection in the solar chromosphere by usinghigh spatial resolution data including polarimetric signals. Magnetic reconnection occurs whenmagnetic field lines of different directions come in contact and change the configuration of the fieldlines. READ MORE

3. Optimization of Non-Local Means filtration for Cone Beam Computed Tomography
University essay fromAbstract : Cone Beam Computed Tomography (CBCT) is a medical imaging technique used to visualize the internals of an object from a set of X-ray images. The X-ray images are taken with a cone shaped X-ray beam at many angles around the object being visualized. The images are then back projected through a volume forming a 3D representation of the object. READ MORE

5. Low Light Video Enhancement along with Objective and Subjective Quality Assessment
University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandlingAbstract : Enhancing low light videos has been quite a challenge over the years. A video taken in low light always has the issues of low dynamic range and high noise. This master thesis presents contribution within the field of low light video enhancement. READ MORE
