Functions

void dip::Clip(dip::Image const& in, dip::Image& out, dip::dfloat low = 0.0, dip::dfloat high = 255.0, dip::String const& mode = S::BOTH)
Clips the sample values in in to a specified range.
void dip::ClipLow(dip::Image const& in, dip::Image& out, dip::dfloat low = 0.0)
Clips the sample values in in, putting all values below low to low.
void dip::ClipHigh(dip::Image const& in, dip::Image& out, dip::dfloat high = 255.0)
Clips the sample values in in, putting all values above high to high.
void dip::ErfClip(dip::Image const& in, dip::Image& out, dip::dfloat low = 128.0, dip::dfloat high = 64.0, dip::String const& mode = S::RANGE)
Clips the sample values in in to a specified range, using the error function.
void dip::Zero(dip::Image const& in, dip::Image& out, dip::dfloat threshold = 128.0)
Zeros the sample values in in that are below threshold.
void dip::ContrastStretch(dip::Image const& in, dip::Image& out, dip::dfloat lowerBound = 0.0, dip::dfloat upperBound = 100.0, dip::dfloat outMin = 0.0, dip::dfloat outMax = 255.0, dip::String const& method = S::LINEAR, dip::dfloat parameter1 = 1.0, dip::dfloat parameter2 = 0.0)
Applies a mapping function according to the input image’s range and the given output range.
void dip::HistogramEqualization(dip::Image const& in, dip::Image& out, dip::uint nBins = 256)
Modifies the image such that its histogram is as flat as possible.
void dip::HistogramMatching(dip::Image const& in, dip::Image& out, dip::Histogram const& example)
Modifies the image such that its histogram is as similar as possible to example.
