cv::Mat rdf::IP::computeHist ( const cv::Mat &  data, int  width, int  numElements = -1, double *  maxBin = 0  )

static

Computes the histogram of data. Data can be any type (it will be reduced to CV_32F).

Parameters

data	The data.
width	The length of the resulting histogram.
numElements	The number elements if data has more elements, it will be downsampled accordingly.
maxBin	The maximal bin of the resulting histogram.

Returns

A 1xN CV_32F. Each element represents a bin computed from data.

void rdf::IP::draw ( const std::vector< cv::Point > &  pts, cv::Mat &  img, unsigned char  val = 255  )

static

cv::Mat rdf::IP::grayscale ( const cv::Mat &  src )

static

Returns the Luminance channel of Luv which is better than the RGB2Gray.

Parameters

src	The source.

Returns

cv::Mat rdf::IP::invert ( const cv::Mat &  src )

static

void rdf::IP::normalize ( cv::Mat &  src )

static

QColor rdf::IP::statMomentColor ( const cv::Mat &  src, const cv::Mat &  mask = cv::Mat(), double  momentValue = 0.5  )

static

C.

Parameters

src	The source.

Returns

double rdf::IP::statMomentMat ( const cv::Mat &  src, const cv::Mat &  mask = cv::Mat(), double  momentValue = 0.5, int  maxSamples = 10000, int  area = -1  )

static

Computes robust statistical moments of an image. The quantiles of an image (or median) are computed.

Parameters

src	The source image CV_32FC1.
mask	The mask CV_32FC1 or CV_8UC1.
momentValue	The moment (e.g. 0.5 for median, 0.25 or 0.75 for quartiles).
maxSamples	The maximum number of samples (speed up).
area	The mask's area (speed up).

Returns

The statistical moment.
