| Abstract(in English) | In this paper, we propose a high-capacity reversible data hiding method for HDR images with the Radiance RGBE format (hereafter, RGBE images). In a previous study, two embedding regions are allocated in an RGBE image, so two different types of information can be embedded and extracted in turn. We extend the embedding algorithm of the previous method to obtain a higher hiding capacity and four embedding regions. Experimental results show that the hiding capacity of the proposed method is three times larger than that of the conventional method. |
