Image watermarking using 2-level DCT and genetic algorithm

The technique of embedding the particular information inside the host image is termed as watermarking. The existence of watermark may be in many different forms which may act as host or the guest depending on what is being embedded into which. The ownership is provided to the image with the help of watermark which will be in the form of digital signature. For authentication of the images, watermarking is the best technique. The proposed work is based on discrete cosine transform technique which explains how a data can be embedded securely in the image. The proposed work is inspired by the genetic approach, in our work we have implemented the training of the images using Genetic algorithm or discrete cosine transform which shows its histogram form and optimizes the images for further processing. With an embedded image containing additional.
