Domain Visible Watermarking Technique on Images Base Paper

Introduction to Domain Visible Watermarking Technique on Images Project:

To protect publicly available image, there is a need to use visible watermarking, which is one type of digital watermarking. This paper discussed about how a visible watermarking technique applies to a host image in the DCT domain. Few significant modifications done to the algorithm in order to make the watermark robust.

Digital watermarking is a process of inserting watermark into a multimedia object to protect the object’s owner’s right. The original and watermark images are divided into blocks and the corresponding DCT coefficients are also need to be observed. For each block of original image, some mathematical calculations need to be done as per algorithm. After all the modifications done to each block of the image, watermarked image will get generated. To protect the quality of watermarked image there is a need to consider and manage both embedding and scaling factors.


In the DCT Domain, a visible watermarking technique has proposed. To exploit the HVS texture sensitivity a mathematical model has developed. This paper discusses about few modifications which need to be done for watermark insertion algorithm to make it more effective for all images and also to increase the robustness of the watermark. Watermark should be used in different portions in different sizes and for different images also it should not available publicly for more robustness. Even when images are printed on paper, to make the watermark more prominent by consider lower values of amin and amax, also higher values of bmin and bmax. Visible watermark is a technique which is used in current digital TV, ecommerce and digital library etc.
