Thesis is concerned with the design of robust digital image watermarking algorithms for copyright protection firstly, an overview of the watermarking system, applications of watermarks as well. The goal of this thesis is to produce two watermarking tools and compare their effectiveness with that of other watermarking tools one of the tools uses a spatial watermarking technique, while the other uses a frequency based spread spectrum technique. The next topic is image watermarking and effects of halftoning on watermarked images watermarking is the process of embedding a secret signal into a host signal in order to verify ownership or authenticity. Recently, the watermarking technique was proposed to solve the problem of protecting the intellectual property in this project, a watermark embedded in the host image by dct transform has been developed.
In this thesis, two new digital image watermarking schemes are proposed in the first scheme, an arnold transform integrated dct-svd based image watermarking scheme is developed the main idea in this scheme is to improve the robustness of the. Watermarking of digital images a project report an invisible image watermarking technique in spatial domain 61 introduction 61 • a spread spectrum watermarking technique for digital images the thesis concludes with a discussion of the advantages and disadvantages of the. Tion technique based on watermarking where if the image is authentic, the distortion due to embeddingcan be completely removed from the watermarked image after the hidden data has been extracted this technique utilizes histogram char-acteristics of the difference image and modi þ es pixel values.
