Abstract:V magistrskem delu podamo pregled izgubnih ter brezizgubnih stiskanj, ki bi se lahko uporabila za shranjevanje večkanalnih površinskih signalov EMG. Podrobneje preučimo posledice izgubnega stiskanja za izvedbo dekompozicije signalov EMG na prispevke posameznih motoričnih enot. Rezultata magistrske naloge sta prototip namizne aplikacije za stiskanje in razširjanje površinskih signalov EMG ter analiza uporabljenih metod stiskanja. Prototipna aplikacija omogoča odpiranje datotek s končnico OTB, branje metapodatkov o signalih iz pripadajočih datotek s končnico XML ter branje in pisanje vrednosti signalov iz in v datoteke s končnico SIG.

Title:LOSSLESS AND LOSSY COMPRESSION OF MULTICHANNEL SURFACE ELECTROMYOGRAMS
Abstract:In this thesis, we provide an overview of lossy and lossless compression methods that could be used for storing multichannel surface EMG signals. In particular, we provide the analysis of lossy compression impacts on the decomposition of EMG signals. The main results include a prototype of a desktop application for compression and decompression of surface EMG signals, and a short analysis of the used compression methods and their impact on decomposition of surface EMG signals. The application supports opening of OTB file types, reading of signal’s metadata from the corresponding XML files, and reading and writing of signal vales to and from SIG data files.
Keywords:lossy compression, lossless compression, surface electromyograms, principal component analysis
