Prodipta Bhowmik, Tanmay Bhattacharya . A Real Time Visible Watermarking Technique using Dual Tree Complex Wavelet Transformation. International Journal of Computer Applications. 124, 17 ( August 2015), 20-23. DOI=10.5120/ijca2015905820
The key idea of this paper is to propose a real-time, self- authenticating, watermarking technique. Here the watermark has been constructed from the image itself using Toeplitz matrix and the embedding region is selected by the user at real-time. Embedding region should be selected from Region of Non Interest (RONI) of the image. Dual Tree Complex Wavelet transformations (DT-CWT) based embedding technique has been applied for the embedding purpose. The key is shared or transferred to the receiver through a secret channel. At the receiving end, the extracted watermark is matched with the matrix generated from the bit-sequence (key) which ensures the originality of the image.
