dcterms:description
V tomto článku prezentujeme výsledky rozsáhlé uživatelské studie metod pro transformaci barevných obrázků na černobílé. Výsledky implikují, že není jedna univerzální transformační metoda, která by produkovala excelentní výsledky pro všechny vstupní barevné obrázky. Methods performing the conversion of color images to grayscale aim to retain as much information about the original color image as possible, while simultaneously producing perceptually plausible grayscale results. Many methods of conversion have been proposed, but their performance has not yet been assessed. In this paper, we present the results of two subjective experiments in which a total of 24 color images were converted to grayscale using seven state-of-the-art conversions and evaluated by 119 human subjects using a paired comparison paradigm. We surveyed nearly 20000 human responses and used them to evaluate the accuracy and preference of the colorto-grayscale conversions. To the best of our knowledge, the study presented in this paper is the first perceptual evaluation of color-to-grayscale conversions. Besides exposing the strengths and weaknesses of the researched methods, the aim of the study is to attain a deeper understanding of the examined field.
