【Abstract】 Image hiding based on blending functions is discussed in this paper. The aim of this paper is to apply the blend function of CAGD to digital image hiding, which helps transfer and store digital images in a secure way. Firstly, our attention is focused on Bernstein functions of Bezier curves, then we apply the algorithm to B spline and center on the discussion of digital image hiding based on B spline and multi knot spline. In this paper, we also discuss the reliability and stability of image hiding and give some results of the state of robust and safety of the experiments.更多还原
