Signal Enhancement for the SPID Corpus

In order to cancel the noise introduced by the ambiance simulation, an adaptive filter based noise cancellation algorithm was applied to the recordings of the SPID corpus. Furthermore, a frequency-domain noise and cross-talk suppression was applied. The two time and time-frequency pots below show examples. The enhanced as well as the original signals are available for the entire corpus parts where the ambiance simualtion was used.

Biosignals Workshop in Erfurt

Also in the week of DAGA but between the 21st to the 23rd March the Biosignals Workshop took place in the protestant monastery of St. Augustine in Erfurt. The topic was innovative processing of bioelectric and biomagnetic signals and was organized by the technical VDE committees „Biosignals“ and „Magnetic Methods in Medicine“. The DSS group (Christin and Eric) participated with two ...
