Abstract :
In this paper a new spatial masking method for watermarking techniques is proposed. The mask is computed using a local and a global reference to image texture. JSEG segmentation algorithm offers an estimation of color texture and some of its parameters are used in our masking method. The proposed masking method is used in a DCT-based watermarking algorithm and results are compared with JND (Just Noticeable Distortion) masking method.
