Robust Invisible Watermarking Using OSTU Method and DWT

Abha Gaur, Akhilesh Pandey

In this work we have devised the invisible watermarking using Haar wavelet function and otsu segmentation. Here we have contributed by providing a threshold parameter to binarise message image using ostus method and analysing a new formulation for Normalised Coefficient parameter. As all watermarking consists of two units i.e. embedding and extracting. In this we also calculate the five parameters i.e. contrast, dissimilarity, homogeneity, angular momentum and entropyee of cover image and message image.
