Function Documentation

cantor_pairing()

template<class T >

T misaxx::imaging::utils::cantor_pairing	(	T	x,
		T	y
	)

Cantor pairing function that transforms two natural numbers into a unique numerical representation of those numbers.

Template Parameters

T

Parameters

x
y

Returns

find_percentile() [1/2]

template<typename T >

T misaxx::imaging::utils::find_percentile ( std::vector< T > &  t_pixels, const double  t_percentile  )

inline

find_percentile() [2/2]

template<typename T >

T misaxx::imaging::utils::find_percentile ( const std::vector< T > &  t_pixels, const double  t_percentile  )

inline

find_percentiles()

template<typename T , typename U >

void misaxx::imaging::utils::find_percentiles ( std::vector< U > &  t_result, std::vector< T > &  t_pixels, const std::vector< double > &  t_percentiles, bool  t_multi_use_nth_element = true  )

inline

Finds percentiles of a vector. NOTE: This function WILL partially sort the vector!

Parameters

t_pixels
t_percentiles	Vector of percentiles to fetch

Returns

List of percentile values with the same order as t_percentiles

huang_shannon2()

template<class T >

size_t misaxx::imaging::utils::huang_shannon2 ( const std::vector< T > &  data )

inline

otsu()

size_t misaxx::imaging::utils::otsu ( const std::vector< int > &  t_histogram )

inline

Calculates Otsu threshold from a histogram. Legacy function until cxxh::math::histogram will take over

Template Parameters

T

Parameters

t_histogram

Returns

tiffread()

cv::Mat misaxx::imaging::utils::tiffread

(

const boost::filesystem::path &

t_path

)

Reads a cv::Mat from TIFF. Supports all types supported by OpenCV

Parameters

t_path

Returns

tiffwrite()

void misaxx::imaging::utils::tiffwrite	(	const cv::Mat &	t_img,
		const boost::filesystem::path &	t_path,
		tiff_compression	t_compression = tiff_compression::none
	)

Writes a cv::Mat to TIFF. Supports all types supported by OpenCV

Parameters

t_img
t_path
