1. Computational diffusion MRI: Tensor-based models for diffusion imaging of the brain
Sammanfattning : .... LÄS MER
2. New Techniques for Estimation of Source Parameters : Applications to Airborne Gravity and Pseudo-Gravity Gradient Tensors
Sammanfattning : Gravity gradient tensor (GGT) data contains the second derivatives of the Earth’s gravitational potential in three orthogonal directions. GGT data can be measured either using land, airborne, marine or space platforms. LÄS MER
3. Evidence for "liveness" in face biometrics
Sammanfattning : Aliveness or "liveness" detection is a novel but crucial topic in biometrics. In this study we will investigate it for face biometrics. The problem is given by the real-time requirements of such a system to be able to avert advanced spoofing attempts, e.g. LÄS MER
4. A Tensor Framework for Multidimensional Signal Processing
Sammanfattning : This thesis deals with ltering of multidimensional signals. A large part of the thesis is devoted to a novel filtering method termed "Normalized convolution". The method performs local expansion of a signal in a chosen lter basis which not necessarily has to be orthonormal. LÄS MER
5. Multi-scale feature tracking and motion estimation
Sammanfattning : This thesis studies the problems of feature tracking and motion estimation and presents an application of these concepts to human-computer interaction. The presentation is divided into three parts. The first part addresses feature tracking in a multi-scale context. LÄS MER
