A module for converting image level values to an array of output values
A module for converting image level values to an array of output values
usage:
var histogram = require('histogram'); var table = levelsToTable(inputBlack, inputWhite, gamma, outputBlack, outputWhite);
where inputBlack, inputWhite, outputBlack, outputWhite values go from 0 to 255, although it supports any range and even negative values.
Gamma is an exponential value, so set it to 1 for a linear transformation.
The function for each value is expressed like so:
R' = outputBlack + (outputWhite - outputBlack) Math.pow((R - inputBlack) / (inputWhite - inputBlack), 1 / gamma)
