Abstract
Robustness is an essential requirement of watermarking schemes so that they can sustain several intentional or unintentional image processing attacks. For such a robust watermarking algorithm, watermark will be embedded into the third level wavelet coefficients of an image that is decomposed by using DWT technique. In this paper the third level watermarking scheme is proposed by three different algorithm and the obtained results are then compared so as to find out that which algorithm performs better under a particular condition. In present study the third level enhanced watermarking scheme for two DWT based watermarking techniques namely alpha blending technique and CDMA-DWT based watermarking scheme is also proposed. The results obtained by these two techniques are further compared and analyzed.
