Removable visible image watermarking algorithm in the discrete cosine transform domain
Abstract. A removable visible watermarking scheme, which operates in the discrete cosine transform (DCT) domain, is proposed for combating copyright piracy. First, the original wat...

A blind watermarking technique in JPEG compressed domain
We proposed a blind watermarking technique to embed the watermark in JPEG compressed domain. Low frequency DCT coefficients are extracted to form an M-dimensional vector. Watermar...

Turbo coding for sample-level watermarking in the DCT domain
Coding at the sample level in still image watermarking takes advantage of avoiding a non-optimum initial diversity stage, used in many watermarking systems for tailoring Gaussian ...

A dual watermarking technique for images
Digital watermarking is the technique in which a visible/invisible signal (watermark) is embedded in a multimedia document for copyright protection. In this paper, we propose a wa...
