Comparative Analysis of Spatial Watermarking Method with & without estimator approach

Neha Y. Joshi, Kavindra R. Jain

In this paper we propose a watermarking method in which Estimator based approach is used. Due to this approach simple spatial method could resist different noise attacks. For the evaluation of Imperceptibility & Robustness of the proposed method we have calculated different quality measure parameters. We have tested watermarked image against different noise attacks at different noise densities. Due to the use of estimator & the parameter so calculated gives the measure of perceptible quality of embedded & extracted images.
