Member Data Documentation

◆ alpha

double nk::image::AdaptHistEqOptions::alpha = 0.4

Shape parameter for the rayleigh / exponential distributions.

Definition at line 129 of file contrast.hpp.

◆ clipLimit

double nk::image::AdaptHistEqOptions::clipLimit = 0.01

Histogram clip fraction in [0, 1]; 0 disables clipping.

Higher values produce more contrast.

Definition at line 117 of file contrast.hpp.

◆ distribution

std::string nk::image::AdaptHistEqOptions::distribution = "uniform"

Target histogram shape:

"uniform" — flat (default)
"rayleigh" — bell-shaped (Rayleigh inverse CDF)
"exponential" — curved (exponential inverse CDF)

Definition at line 126 of file contrast.hpp.

◆ nBins

int nk::image::AdaptHistEqOptions::nBins = 256

Histogram bin count.

Definition at line 120 of file contrast.hpp.

◆ numTilesC

int nk::image::AdaptHistEqOptions::numTilesC = 8

NumTiles along the column axis.

Definition at line 113 of file contrast.hpp.

◆ numTilesR

int nk::image::AdaptHistEqOptions::numTilesR = 8

NumTiles along the row axis.

Image is partitioned into numTilesR × numTilesC contextual regions.

Definition at line 110 of file contrast.hpp.

◆ range

std::string nk::image::AdaptHistEqOptions::range = "full"

Output intensity range:

"full" — full range of the image class (default)
"original" — limited to the input's actual [min, max]
