Keypoint Description by Symmetry Assessment -- Applications in Biometrics

Autor: Mikaelyan, Anna, Alonso-Fernandez, Fernando, Bigun, Josef

We present a model-based feature extractor to describe neighborhoods around keypoints by finite expansion, estimating the spatially varying orientation by harmonic functions. The iso-curves of such functions are highly symmetric w.r.t. the origin (a

Compact multi-scale periocular recognition using SAFE features

Autor: Alonso-Fernandez, Fernando, Mikaelyan, Anna, Bigun, Josef

In this paper, we present a new approach for periocular recognition based on the Symmetry Assessment by Feature Expansion (SAFE) descriptor, which encodes the presence of various symmetric curve families around image key points. We use the sclera cen

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

Analitical study of the Schönbucher-Wilmott model of the feedback effect in illiquid markets

Autor: Mikaelyan, Anna

This master project is dedicated to the analysis of one of the nancialmarket models in an illiquid market. This is a nonlinear model. Using analytical methods we studied the symmetry properties of theequation which described the given model. We calle

Models of self-financing hedging strategies in illiquid markets: symmetry reductions and exact solutions

Autor: Bordag, Ljudmila A., Mikaelyan, Anna

Publikováno v: Lett. Math. Phys. 96, pp. 191-207, 2011

We study the general model of self-financing trading strategies in illiquid markets introduced by Schoenbucher and Wilmott, 2000. A hedging strategy in the framework of this model satisfies a nonlinear partial differential equation (PDE) which contai
