چکیده
Embedding a digital signal with information which cannot be removed easily is called „Digital watermarking‟. In visible watermarking of images, a secondary image is embedded in a primary image such that watermark is intentionally perceptible to human observer.The present work aims at visible watermarking algorithm based on luminance parameters in DCT domain. Visible watermarking is a type of digital watermarking used for protection of publicly available images. The growth of computer networks has boosted the growth of the information technology sector to a greater extent. There is a trend to move from conventional libraries to digital libraries. Visible watermarking is a type of digital watermarking used for protection of publicly available images. In this paper, the proposed work consists of visible watermarking scheme that is applied into the host image in the DCT domain. The algorithm will be implemented on MATLAB platform.

متن کاملRobust Colour Image Watermarking Scheme Based on Feature Points and Image Normalization in Dct Domain
Geometric attacks can desynchronize the location of the watermark and hence cause incorrect watermark detection. This paper presents a robust colour image watermarking scheme based on visually significant feature points and image normalization technique. The feature points are used as synchronization marks between watermark embedding and detection. The watermark is embedded into the non overlap...
متن کاملA Modified Digital Image Watermarking Scheme Based on Nonnegative Matrix Factorization
This paper presents a modified digital image watermarking method based on nonnegative matrix factorization. Firstly, host image is factorized to the product of three nonnegative matrices. Then, the centric matrix is transferred to discrete cosine transform domain. Watermark is embedded in low frequency band of this matrix and next, the reverse of the transform is computed. Finally, watermarked ...
