APPARATUS AND METHOD FOR CONVERTING HCI (HUE-CHROMA-INTENSITY) COLOR MODEL, ROBUST AGAINST ILLUMINATION CHANGES

摘要

Disclosed is a technique for converting a color model of an image in order to extract a subject from the image. The present invention is more resistant to an illumination effect such as highlight than a case in which other color models are used by using a Hue-Chromaticity-Intensity color model. Therefore, the present invention can accurately extract the subject from the image in which the illumination effect is included.
