Savneet Kaur, Kumud Sachdeva . Adaptive Watermarking based on Tree Structure based using 3-4 Level DWT and DCT. International Journal of Computer Applications. 128, 18 ( October 2015), 1-4. DOI=10.5120/ijca2015906608
An adaptive watermarking scheme provides more contribution related to DWT for image content. In this paper an adaptive watermarkingschemeusing tree structure is proposed.This watermarking method makes use of a classificationprocedure for identifying various parts of the image which can be watermarkedby using the most suited modulation DWT. This classificationdependson a reference image which is derived from the image itself and aprediction of it necessarywhich has the property of being invariant change tothe watermark insertion process.In this paper the results on the basis of psnr, mse, entropy and embedding capability, mean ssim, just noticeable difference have been found. This algorithm is better for the psnr and embedding capability as compared to the previous algorithm. Proposed algorithm has improved successful watermarking image for future work with other compatible algorithm for the security purpose.
