21. Fast Parametric Registration and Machine Learning Analysis of Whole-Body MRI Volumes for Age-Related Changes
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : Using an extensive dataset provided by the UK Biobank, this project intended to develop methods for registering whole body MRI volumes and analyzing the changes in the body due to ageing. The registration method is developed using the pTV image registration module, which employs a fast registration approach based on parametric total-variation to align volumes to the same local coordinate frames of the reference, for point-wise anatomical region correspondence.

24. Data Mapping Across Compact Cellular Tissues of Varying Morphology
University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisationAbstract : A problem with cellular image data from plant tissues is that it is difficult to compile and compare data from different specimens due to their varying morphology. In this thesis, a method for compiling image data from different tissues in a unified geometry is developed and evaluated on early floral buds of Arabidopsis thaliana. READ MORE

25. Automatic Change Detection in Visual Scenes
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : This thesis proposes a Visual Scene Change Detector(VSCD) system which is a system which involves four parts, image retrieval, image registration, image change detection and panorama creation. Two prestudies are conducted in order to find a proposed image registration method and a image retrieval method. READ MORE
