本发明提供一种可视资讯隐藏方法，适用于行动装置及电子设备之拍摄媒体。可视资讯隐藏方法包括对装置拍摄之原始影像，于原始影像中决定至少一影像嵌入区域。对此影像嵌入区域计算出RGB三个色调平均值。依据三色调平均值选出适合嵌入的色调。并将浮水印影像嵌入于选出之区域色调内，嵌入方式系依可视资讯以调整区域色调平均值。嵌入后之媒体外观，人眼视觉不易察觉，唯透过装置对直方图区间进行调整，即可将隐藏资讯，以人眼可视方式显示。; computing a red mean value, a green mean value, and a blue mean value from the image embeddable region; choosing, according to a threshold value, a color of the region to embed a watermark image; and embedding the watermark image into the original image. The watermark image embedded in the original image is not easy to see by human eyes. Only by adjusting the color histogram of the display device, the watermark image is visiable for human eyes. |
