Abstract
This paper proposes two data embedding algorithms for T-spline surfaces, one is suitable for steganography, and the other for robust shape-preserving watermarking. For steganography, we embed data into the points on T-spline surfaces by using constrained optimization method. For robust shape-preserving watermarking, we use the local knot insertion of T-spline surfaces. The experiment results and their analyses are also presented.
