A significant effort has been put in designing watermarking algorithms during the last decade. But today, the watermarking community needs some advanced attacks and fair benchmark...
— In this work, we examine a family of anti-collusion codes using the principle of “Orthogonal Spreading followed by the Inverse Fourier Transform (OSIFT)” as introduced in [...
We propose a novel and robust hashing paradigm that uses iterative geometric techniques and relies on observations that main geometric features within an image would approximately ...
