A new approach to the problem of impulsive-noise reduction for color images is introduced. The major advantage of the technique is that it filters out the noise component while adapting itself to the local image structures. In this way the algorithm is able to eliminate strong impulsive noise while preserving edges and fine image details. As the algorithm(More)
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

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)
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 segmentation method of multispectral human eye images suitable in ophthalmic diagnosis of structural retinal features characteristic for glaucoma and diabetic retinopathy diseases is presented. A multispectral imaging was realized in 21 spectral windows, between 400nm and 740nm, on a base of liquid crystal tunable filter and a high sensitivity(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)
Design tools integration is a central issue in distributed design methodologies of SoCs. The paper presents methods and tools for distributed tools integration based on a markup language (XML) which supports universal description of tools, straightforward storage, search and retrieval of tool descriptions, as well as remote invocation of tools, and in(More)
