Member Function Documentation

int LIBCP::Histogram::binarize (  Image *  dst, Image *  src, int  threshold )  [static]

Binarize image using a local hysteresis threshold

int LIBCP::Histogram::gammaCorrection (  Image *  dst, Image *  src, float  r = 2.2f )  [static]

Gamma correction of the input image

int LIBCP::Histogram::hysteresisThreshold (  Image *  dst, Image *  src, const int  low, const int  up )  [static]

Performs a hysteresis thresholding over the input image.

void LIBCP::Histogram::makeHistogram (  Image *  img, histo *  histogram )  [static]

Compute the histogram of an image

int LIBCP::Histogram::markLevelRange (  Image *  dst, Image *  src, int  rangeStart, int  rangeStop, Color *  col, bool  background = true )  [static]

Mark a level range in the image with a selected color. The background may be cleared or it may retain the orginal image

int LIBCP::Histogram::negativeImage (  Image *  dst, Image *  src )  [static]

Compute the negative image

int LIBCP::Histogram::stretchContrast (  Image *  dst, Image *  src )  [static]

Automatic full range stretching of the input image
