2. 1. Compact orientation and frequency estimation with applications in biometrics : Biometrics on the orientation express

   Author : Anna Mikaelyan; Josef Bigun; Kenneth Nilsson; Raffaele Cappelli; Högskolan i Halmstad; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Automatic feature extraction still remains a relevant image and signal processing problem even tough both the field and technologies are developing rapidly. Images of low quality, where it is extremely difficult to reliably process image information automatically, are of special interest. READ MORE

4. 2. Estimation of Nonlinear Dynamic Systems : Theory and Applications

   Author : Thomas B. Schön; Fredrik Gustafsson; Simon Godsill; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear estimation; system identification; Kalman filter; particle filter; marginalized particle filter; expectation maximization; automotive applications; Automatic control; Reglerteknik;

   Abstract : This thesis deals with estimation of states and parameters in nonlinear and non-Gaussian dynamic systems. Sequential Monte Carlo methods are mainly used to this end. These methods rely on models of the underlying system, motivating some developments of the model concept. READ MORE

5. 3. Polynomial expansion for orientation and motion estimation

   Author : Gunnar Farnebäck; Gösta Granlund; Linköpings universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : This thesis introduces a new signal transform, called polynomial expansion, and based on this develops novel methods for estimation of orientation and motion. The methods are designed exclusively in the spatial domain and can be used for signals of any dimensionality. READ MORE

6. 4. Spatial domain methods for orientation and velocity estimation

   Author : Gunnar Farnebäck; Gösta Granlund; Linköpings universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : In this thesis, novel methods for estimation of orientation and velocity are presented. The methods are designed exclusively in the spatial domain.Two important concepts in the use of the spatial domain for signal processing is projections into subspaces, e.g. READ MORE

7. 5. Vehicle Size and Orientation Estimation Using Geometric Fitting

   Author : Christina Carlsson; Mille Millnert; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Over the years imaging laser radar systems have been developed for both military and civilian applications. Among the applications we note collection of 3D data for terrain modelling and object recognition. One part of the object recognition process is to estimate the size and orientation of the object.
