In PyAudioAnalysis > audioFeatureExtraction.py, there is stEnergyEntropy.

I can not understand what is the difference between 'Eol' and 'numpy.sum(sub_wins ** 2.)'

Plz let me know, the differece of two things( 'Eol' and 'numpy.sum(sub_wins ** 2.)')

Gamma correction is among the things most often done wrong by graphics programming novices. It's almost as bad as missing scene-related color transforms and linear volume sliders in the average video game. The code example in the readme should definitely mention to adjust.Gamma(img, 1/2.2) before doing any color mixing and adjust.Gamma(img, 2.2) before saving back to file (for as long as _bild

Acurite TXR, 5n1, 6045 and possibly others like the new Atlas weather station use parity in addition to checksums for integrity checking.

Currently the parity isn't verified, it's only looked at in verbose mode.

I've noticed I seem to get messages for non-existent devices from time to time. I suspect the message is mangled but the checksum still passes. The parity check in addition to the

I recently stumbled upon a bothering fact when using the pywt. When we use the default "symmetric" padding, the inverse wavelet transform is not the adjoint of the wavelet transform (and it's not the mathematical inverse of the wavelet transform, "only in one direction").

However, if you use the "zero" padding the adjoint property is verified (not the inverse property). And if you use the

I noticed that the docs for EvaluationStatus indicate that "reported" is an acceptable value, but the code for EvaluationStatus itself will not accept it.

obspy.core.event.Pick(time=time, waveform_id=wid, phase_hint="P", evaluation_status="reported")

returns

`ValueError: Setting attribute "evaluation_status" failed. Value "reported" could not be converted to type "Enum(["preliminary

I noticed since v0.0.10 release, GNSS-SDR supports Enabled extended coherent integration times. How can I do that? for example, if I am going to use coherent_integration_time_ms=5, besides the following configurations,

Acquisition_1C.coherent_integration_time_ms=5
Acquisition_1C.doppler_step=150

what else should I do?

And how can I configure the non-coherence integration coun
