void fwData::Histogram::addPixel ( float pixel )

Add the given pixel value into the histogram.

This void will chose the right bins where the pixel must be added (if the bins width parameter is greater than 1).

Parameters

pixel the pixel value to be added into the histogram.

void fwData::Histogram::initialize	(	float	min,
		float	max,
		float	binsWidth
	)

Initialize the histogram.

Parameters

min	Defines the lower pixel value of the image that this histogram belongs to.
max	Defines the upper pixel value of the image that this histogram belongs to.
binsWidth	Defines the desired bins' width in order to classify pixels.

bool fwData::Histogram::isInRange ( float _pixel )

Return true if the given pixel value is set within histogram's boudaries.

Parameters

_pixel the pixel value

Returns: true if the pixel value is set within histogram's boundaries.

Definition at line 127 of file src/fwData/Histogram.cpp.
