A world where documents talk, objects carry secrets, and your veins guide medical tools may be closer than it seems. A team of researchers from Universidad Carlos III de Madrid (UC3M), the ...

In image watermarking, the watermark robustness to geometric transformations is still an open problem. Using invariant image features to carry the watermark is an effective approach to addressing this ...

A dual-image watermarking approach is presented in this research. The presented work utilizes the properties of Hessenberg decomposition, Redundant discrete wavelet transform (RDWT), Discrete cosine ...
