摘要： In embedding a watermark, it is possible to effectively detect the watermark even in case of rotating, cutting, and enlarging/shrinking an image by designing the watermark to be robust against geometric modification and embedding the watermark as 2-dimensional form, for example radial or concentric form. Also, in detecting a watermark, it is possible to detect a peak formed by the watermark through the convolution of the watermark and an input image while accommodating a size of the generated watermark, thereby effectively detecting the watermark using correlation between the input image and the watermark.
