Visual Attention and Saliency Detection

We visually evaluated the accuracy of color prediction methods that derive the colorimetric values of an object from the sensor responses of a digital still camera. Although an objective measure such as colorimetric error is often used in such evaluations, subjective evaluation is also required to ensure the practicality and acceptability of image archiving for cultural heritage. We conducted visual experiments in which observers evaluated the color matching accuracy between original Hizen porcelain and nishiki-e (Japanese woodblock prints) and their printed reproductions. Results demonstrate that the metamer estimation method, a color prediction method previously proposed by the authors, outperforms conventional methods and is therefore suitable for practical use.
