ОЦЕНКА ТОЧНОСТИ АВТОМАТИЧЕСКИХ АЛГОРИТМОВ КОРРЕКЦИИ ЦВЕТОВЫХ СДВИГОВ ИЗОБРАЖЕНИЙ

Abstract

Methods of accuracy evaluation of automatic color cast correction algorithms are reviewed. Author analyzed the most common method, which is to calculate the chromaticity of color cast and compare it with the chromaticity measurement of achromatic objects on established image datasets. Author proposes new method for accuracy evaluation — colorist prepares reference images and comparison is carried out by calculating color difference between the pixels of the reference image and image processed by algorithm. New method allowed to consider the peculiarities of human color perception.
