A Middle Bird's cable: ... " If in The Rainy Island of Every Day Struggle you cannot find a bird of paradise just get a wet hen. " ... Summary In this monograph we consider the problem of modeling curves together with the estimation of their length via various interpolation schemes (i.e. piecewise-polynomials) based on discrete reduced data
We propose the method of human identification based on the reduced kinematic data of the gait. In the first stage the pose descriptions of the given skeleton model are reduced by the linear principal component analysis. We obtain the ndimensional motion trajectories of principal components. Afterwards, we use two approaches: feature extraction and dynamic(More)

The aim of the work presented in this paper is to investigate experimentally the behavior of different types of anisotropic diffusion schemes. The efficiency of the filters based on the anisotropic diffusion is determined to large extent by the properties of the conductance function in the PDE equation, which describes the diffusion process. Changing the(More)
The number of patients with heart failure implantable cardiac electronic devices (CIEDs) is growing. Hospitalization rate in this group is very high and generates enormous costs. To avoid the need for hospital treatment, optimized monitoring and follow-up is crucial. Remote monitoring (RM) has been widely put into practice in the management of CIEDs but it(More)
This paper presents numerical research and experiments giving rise to developed algorithm to connect into form of mosaic, images from the capsule endos-copy. In order to apply the algorithm, combined images must have a common area where the correspondence of points is determined. That allows to determine the transformation parameters to compensate movement(More)
The paper is devoted to the gait identification challenges. It evaluates human abilities to recognize gait on the basis of skeleton animations. Further, it proposes the method of gait identification based on the kinematical data .The feature extraction approach and supervised learning are applied. To explore the most individual joints movements, aggregated(More)
