Abstract. In this paper we present a new efficient watermarking scheme for images. The basic idea of our method is to alter the colors of the given image in a suitable but imperce...

In this paper, we describe a new framework for watermarking 3D objects via their contour information. Unlike most conventional 3D object watermarking techniques, for which both in...

The distribution of the wavelet coefficients in 2-D discrete wavelet transform (DWT) subspaces can be well described by a Gaussian mixture statistical model. In this paper, a secr...
