The paper describes three lossy data compression techniques based on the principal
component analysis (PCA), which are compared using the image compression task. The …

Wavelet-based image compression provides substantial improvements in picture quality at
higher compression ratios. Haar wavelet transform based compression is one of the …

In the process of designing automatic control system it is very important to have an accurate
model of the controlled process. Approaches to modelling dynamic systems presented in the …

In this paper we propose a new method for evolutionary selection of parameters and
structure of neuro-fuzzy system for nonlinear modelling. This method allows maintain the …

Efficient storage and transmission of medical images in telemedicine is of utmost importance
however, this efficiency can be hindered due to storage capacity and constraints on …

The presented here paper describes a new approach to the video compression problem.
Our method uses the neural network image compression algorithm which is based on the …

This paper describes a concept of algorithm dedicated to video compression. In our
approach we use an algorithm named the predictive vector quantization (PVQ). Into this …

Video and image compression technology has evolved into a highly developed field of
computer vision. It is used in a wide range of applications like HDTV, video transmission …

In this paper, we present and discuss experimental results of a new concept of algorithm for
video compression. It is named Predictive Vector Quantization (PVQ) and incorporates …

A denoising algorithm for computed tomography images is proposed. The presented method
of noise reduction uses Markov Random Field (MRF) model, Gaussian filter and adaptive …
