Function Documentation

radprof() [1/3]

template<typename vecT , typename eigenImT1 >

void mx::improc::radprof	(	vecT &	rad,
		vecT &	prof,
		const eigenImT1 &	im,
		bool	mean = false,
		double	dr = 1
	)

Calculate the the radial profile.

The median radial profile is calculated by rebinning to a 1 pixel grid. This version calculates a centered radius image.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Template Parameters

vecT	the std::vector-like type to contain the profile
eigenImT1	the eigen-array-like type of the input image

Parameters

[out]	rad	the radius points for the profile. Should be empty.
[out]	prof	the median image value at the corresponding radius. Should be empty.
[in]	im	the image of which to calculate the profile
[in]	mean	[optional] set to true to use the mean. If false (default) the median is used.

radprof() [2/3]

template<typename vecT , typename eigenImT1 , typename eigenImT2 >

void mx::improc::radprof	(	vecT &	rad,
		vecT &	prof,
		const eigenImT1 &	im,
		const eigenImT2 &	mask,
		bool	mean = false
	)

Calculate the the radial profile.

The median radial profile is calculated by rebinning to a 1 pixel grid. This version calculates a centered radius image.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Template Parameters

vecT	the std::vector-like type to contain the profile
eigenImT1	the eigen-array-like type of the input image
eigenImT2	the eigen-array-like type of the radius and mask image
eigenImT3	the eigen-array-like type of the mask image

Parameters

[out]	rad	the radius points for the profile. Should be empty.
[out]	prof	the median image value at the corresponding radius. Should be empty.
[in]	im	the image of which to calculate the profile
[in]	mask	1/0 mask, only pixels with a value of 1 are included in the profile
[in]	mean	[optional] set to true to use the mean. If false (default) the median is used.

radprof() [3/3]

template<typename vecT , typename eigenImT1 , typename eigenImT2 , typename eigenImT3 >

void mx::improc::radprof	(	vecT &	rad,
		vecT &	prof,
		const eigenImT1 &	im,
		const eigenImT2 &	radim,
		const eigenImT3 *	mask,
		bool	mean = false,
		typename eigenImT1::Scalar	minr = 0
	)

Calculate the the radial profile.

The median radial profile is calculated by rebinning to a 1 pixel grid.

Template Parameters

vecT	the std::vector-like type to contain the profile
eigenImT1	the eigen-array-like type of the input image
eigenImT2	the eigen-array-like type of the radius and mask image
eigenImT3	the eigen-array-like type of the mask image

Parameters

[out]	rad	the radius points for the profile. Should be empty.
[out]	prof	the median image value at the corresponding radius. Should be empty.
[in]	im	the image of which to calculate the profile
[in]	radim	image of radius values per pixel
[in]	mask	[optional] 1/0 mask, only pixels with a value of 1 are included in the profile. Set to 0 to not use.
[in]	mean	[optional] set to true to use the mean. If false (default) the median is used.

radprofim() [1/2]

template<typename radprofT , typename eigenImT >

void mx::improc::radprofim	(	radprofT &	radprof,
		eigenImT &	im,
		bool	subtract = false,
		bool	mean = false
	)

Form a radial profile image, and optionally subtract it from the input.

The radial profile is calculated using linear interpolation on a 1 pixel grid. This version calculates a centered radius image.

Template Parameters

radprofT	the eigen array type of the output
eigenImT	the eigen array type of the input

Parameters

[out]	radprof	the radial profile image. This will be resized.
[in]	im	the image to form the profile of.
[in]	subtract	[optional] if true, then on ouput im will have had its radial profile subtracted.
[in]	mean	[optional] set to true to use the mean. If false (default) the median is used.

Parameters

[out]	radprofIm	the radial profile image. This will be resized.
	im	[in the image to form the profile of.
[in]	rad	an array of radius values for each pixel
[in]	mask	[optional 1/0 mask, only pixels with a value of 1 are included in the profile. Can be nullptr.
[in]	subtract	if true, then on ouput im will have had its radial profile subtracted.
[in]	mean	[optional] set to true to use the mean. If false (default) the median is used.
