Description: In this project, an image watermarking technique based upon a z transform is proposed and analyzes that, how it is resistant to attacks. The redundant transform provides an over complete representation of the image which facilitates the identification of significant image features via a simple correlation operation across scales. Although the watermarking algorithm is image adaptive, it is not necessary for the original image to be available for successful detection of the watermark. The performance and robustness of the proposed technique is tested by applying common image-processing operations such as filtering, re-quantization, and JPEG compression. A quantitative measure is proposed to objectify performance; under this measure.
