In this work, we propose a new algorithm for the computation of Tchebichef moments by
means of a recurrence relation with respect to order and the Gram–Schmidt process, which …

The psychovisual technique has brought about significant improvement in pursuing image
analysis and image reconstruction. The psychovisual threshold can be utilized to find the …

With the era of rapid technology in multimedia, the copyright protection is very important to
preserve an ownership of multimedia data. This paper proposes an image watermarking …

Because of the facility of accessing and sharing digital images through the internet, digital
images are often copied, edited and reused. Digital image watermarking is an approach to …

This paper proposes a blind and robust image watermarking technique using Discrete
Cosine Transform (DCT) for copyright protection on color images called BRIW-DCT. Each …

Digital watermarking is an alternative solution to prevent unauthorized duplication,
distribution and breach of ownership right. This paper proposes a watermarking scheme for …

Image compression leads to minimize the storage-requirement of an image by reducing the
size of the image. This paper presents a bit allocation strategy based on psychovisual …
