Collection, analysis and representation of memory color information

Abstract

Memory color plays an important role in the perceptual process. The aim of this research is to collect, analyze and represent memory color data for certain natural scenes objects: sky, grass and tree leaves. To emphasize reliable data collection, we consider several sources: (a) psychophysical experiment; (b) multispectral image; (c) standard image database and (d) random image collection. Moreover, we consider different daylight conditions and locations. We perform an in-depth analysis of the collected information in the CIE-xy chromaticity space and present the natural scene objects as a memory color ellipse or polygon. Finally, we demonstrate a potential use of the collected information for natural image segmentation and enhancement.
