The paper proposes a new image watermarking technique for digital media that can embed a specified watermark image in the cover image without affecting the imperceptibility and increase the security of watermarks. Watermarking techniques based on DCT (Discrete Cosine Transform) and Wavelet Transform are studied, whereas by using wavelet packet transform the robustness of the technique can be achieved...
In this paper, a new image watermarking technique has been adopted that can embed a specified watermark image in the cover image without affecting the imperceptibility and increase the security of watermarks. Watermarking techniques based on wavelet transform are reported in many literatures but robustness and security using wavelet packets are better when compared to wavelet transform. An attempt...
