pyruct's Issues

Bug with Hilbert transform and filtering

There is a bug in the Hilbert transform and filtering of the rf-signals due to differences between corresponding packages in Matlab and Python. In python, axis=0 should be included. Correction:

In /pyruct/reconstruction/cpuReconUS.py --> analyticalSigMat = hilbert(sigMatN, axis=0)

In /pyruct/preprocessing/filterBandPass.py --> sigMatF = filtfilt(lowF, highF, sigMat, padlen=0, axis=0)

In /pyruct/reconstruction/cpuReconUS.py --> sigMatN = sigMatNormalizeUS(sigMatF) [This is not needed anymore once the filtering is done correctly]
