21. Image Sequence Analysis for Tracking of Moving Objects
Sammanfattning : There are a number of different algorithms for object motion estimation in image sequences. Almost every algorithm is based on one of three different mathematical methods. An overview of these methods is given, together with some published application examples on object tracking. LÄS MER
22. Novel Approaches for Application of Principal Component Analysis on Dynamic PET Images for Improvement of Image Quality and Clinical Diagnosis
Sammanfattning : Positron Emission Tomography, PET, can be used for dynamic studies in humans. In such studies a selected part of the body, often the whole brain, is imaged repeatedly after administration of a radiolabelled tracer. LÄS MER
23. Quality and motion estimation for image sequence coding
Sammanfattning : Since the advent of television obtaining high perceived quality using a limited bandwidth has been an important issue. This thesis proposes methods inspired and based on the human visual system for exploitation of temporal and perceptual redundancy in image sequences to achieve lower coding rate and/ or higher visual quality.

24. Dynamic Programming for Ultrasound Image Analysis of Atherosclerosis
Sammanfattning : Cardiovascular diseases, due to atherosclerosis, are among the most common causes of death in the industrialized world. Atherosclerotic plaque composition as well as arterial diameter and wall thickness can be used to predict the risk of cardiovascular disease. These risk factors can be assessed non-invasively by ultrasound. LÄS MER
25. A Sequence of Essays on Sequences of Auctions
Sammanfattning : Essay I (with Gagan Ghosh and Heng Liu). The existence of declining prices in sequential auctions is a well-documented empirical pattern. Three explanations that can explain the puzzle are bidders being risk averse, loss averse, or ambiguity averse. LÄS MER
