T.Sridevi, K.Swapna, V.Vijay Kumar . Comparative Analysis of Normalization based Image Watermarking Techniques. International Journal of Computer Applications. 27, 3 ( August 2011), 37-43. DOI=10.5120/3279-4461
This paper presents a comparative study of watermarking schemes. The embedding of watermark is performed after the image normalization. By normalization process the normalized image achieves invariance properties against geometric attacks which include rotation, scaling and translation of an image. Watermarking is done using five methods DCT Zigzag, DCT blocks, DWT, Zernike transform, SVD-DCT. Similarity measures are calculated in order to compare the five watermarking schemes.
