Detailed Description

Perform IQ demodulation on an image.

Public Member Functions
std::shared_ptr< SharedImage >	demodulate (const SharedImage &image, double samplingFrequency, double demodulationFrequency, int decimationFactor, double signalFractionalBandwidth=1.0, int filterLength=101) const
	Perform IQ demodulation on the y-axis of the given image and the given frequency.

Member Function Documentation

std::shared_ptr< SharedImage > ImFusion::US::IqDemodulation::demodulate	(	const SharedImage &	image,
		double	samplingFrequency,
		double	demodulationFrequency,
		int	decimationFactor,
		double	signalFractionalBandwidth = 1.0,
		int	filterLength = 101 ) const

Perform IQ demodulation on the y-axis of the given image and the given frequency.

Parameters

image	The image to demodulate
samplingFrequency	The sampling frequency of the image in the y-axis
demodulationFrequency	The frequency to demodulate the image with
decimationFactor	Desired decimation factor while demodulating. The output image will have a height of image.height() / decimationFactor. If image.height() is not divisible by decimationFactor, the spacing will be adjusted accordingly.
signalFractionalBandwidth	The fractional bandwidth (relative to the demodulation frequency) to retain during the demodulation.
filterLength	The length of the FIR filter to use for lowpass filtering the demodulated signal
