This paper presents a private subdivision surface watermarking algorithm. The subdivision schemes include Doo-Sabin Subdivision and Loop Subdivision. The subdivision surface watermarking algorithm includes three main steps as followings. First, the resultant watermarked image minus the original image is the watermark information. The image watermarking algorithm is based on the Fourier transform. Then, the watermark information is scaled down and embedded in one part of the x-coordinate of the subdivision surface. So, the watermarked subdivision surface is obtained. Finally, the x-coordinate of the test subdivision surface is amplified for more effective recovery of watermarks during extraction with original subdivision surface according to the addition property of the Fourier transform. Experimental results prove that our algorithm is resistant to some attacks including noise addition, cropping, rotation, translation, scaling and filter. |
