Metody zpracování balistokardiografie

Abstract

Bachelor thesis deals with design and development of software tool for complex processing and analysis of balistocardiographic signal (BCG). The software was developed in an interactive programming environment and the Matlab scripting programming language in the form of a graphical user interface (GUI). Signal processing means primarily its filtration and treatment for subsequent analysis. On the basis of literary research, linear frequency selective filters and a wavelet transform filter were implemented. The application also allows frequency analysis and signal processing to calculate pulse rate. The individual methods used are tested on synthetic and real data. In the last part, selected methods of comparison are based on objective evaluation in the form of signal-to-noise ratio (SNR).
