VIDEO WATERMARKING DEVICE, SYSTEM FOR EVALUATING A VIDEO WATERMARKING ALGORITHM USING THE SAME DEVICE AND METHOD FOR EVALUATING A VIDEO WATERMARKING ALGORITHM
摘要
PURPOSE: A video watermark insertion device, system and method for evaluating a watermarking algorithm using the same are provided to quantitively measure toughness performance of an watermark algorithm. CONSTITUTION: A watermark inserting unit(110) inserts a watermark including user information into a video content. According to deformation kind and intensity of video, a video transforming unit(120) performs video deformation about the content. A watermark detecting unit(130) detects watermark from a watermarked content. The water mark detecting unit outputs roughness information of a watermarking algorithm.
