Digital image hiding using curvelet transform

This paper presents a digital image hiding technology by using the curvelet transform. Firstly, apply Arnold transform to original image; Secondly, apply curvelet Transform to the original image and the open image, gaining their curvelet coefficients; Thirdly, interpolate their curvelet coefficients; Finally, reconstruct the image by using Inverse curvelet Transform, and thus get the result image. Simulation results show that this approach is easy to use and safety.
