文摘

A transform-based watermarking algorithm for copyright of 3D images is proposed. The algorithm uses DWT and SVD transforms to utilize their individual properties. A watermark is embedded in the center image using a chaos-based embedding scheme. The watermark is extracted blindly from the center, left-eye, and right-eye views. High performance results obtained for imperceptibility, robustness, and capacity.
