Signal Processing

Detailed Description

This module includes signal processing algorithms.

Functions
void	cv::signal::resampleSignal (InputArray inputSignal, OutputArray outSignal, const int inFreq, const int outFreq)
	Signal resampling.

Function Documentation

resampleSignal()

void cv::signal::resampleSignal	(	InputArray	inputSignal,
		OutputArray	outSignal,
		const int	inFreq,
		const int	outFreq
	)

Python:
	cv.signal.resampleSignal(	inputSignal, inFreq, outFreq[, outSignal]	) ->	outSignal

#include <opencv2/signal/signal_resample.hpp>

Signal resampling.

Parameters

[in]	inputSignal	Array with input signal.
[out]	outSignal	Array with output signal
[in]	inFreq	Input signal frequency.
[in]	outFreq	Output signal frequency. Signal resampling implemented a cubic interpolation function and a filtering function based on Kaiser window and Bessel function, used to construct a FIR filter. Result is similar to scipy.signal.resample.
