Fractal transform based large digital watermark embedding and robust full blind extraction
The aim of this demonstration is to present the ongoing performance of our R. and D. watermarking scheme software. The proposed illustrations cover a large panel of original images (in grey levels and colors), signatures and attacks. Evaluation is performed according to ratio, visibility and robustness. All the results (excepting Stirmark cracker) are obtained using a full blind extraction, in other words the extraction step requires neither the original image nor the signature itself.
