Abstract
In this study, a real-time fast parallelized processing technique for C-point locations is presented. Singularity detector adopting a multiscale wavelet transform is used for impedance cardiography signal processing. Both theoretical analysis and experimental results show the method reliability and sensitivity. Moreover, the algorithm noise immunity has been tested adding Gaussian noise with a variable variance to the real ICG signal. Test results with minimum interferences from noise and artefacts have been obtainedI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
