Abstract


Watermarking is used mostly for multimedia data copyright protection. This paper introduces the Transformation Framelet (FLT) for watermarking digital images. In this technique, the FLT is used to create an original image and watermark the low (LL) frequency subband of an original image in LL subband of an image watermarking. Simulation results demonstrate, in terms of a wide range of traditional attaches, that this approach is imperceptible and stable. MATLAB software version 2014 was used for simulation. Experiments on gray scale and colored images were performed in this work.
