[Poster Presentation] Color Modulation Conditions for Imperceptible Information Hiding by Use of Temporal Color Fusion of Human Visual System
Kazuki Hoshi, Tomokazu Shiga (UEC)
Abstract (in Japanese) (See Japanese page) 
(in English) Modulation conditions that suppress flicker and color distortion in information hiding technique with color modulation were obtained from subjective evaluation experiments using color pairs generated in the CIE XYZ color space. The results show that when the modulation direction is $-45^circ$ in CIELAB color space and the color difference $it{Delta}E_{mathrm{00}}$ of the color pair is 15, flicker is imperceptible. Analysis with the DKL color space indicated that the greater the distance between the color pairs, the greater the visibility of flicker. It suggested that change in cone stimulation is a factor in flicker visibility.
