초록

본 논문에서는 웨이블릿 기반의 이미지 워터마킹 방법을 제안하고자 한다. 제안한 방법은 원영상의 주파수 영역에 의사 잡음 코드를 첨가하여 워터마크 된 디지털 영상을 만드는 것이다. 또한, 원영상은 워터마킹 검출을 위해 사용되어지고, 부가되는 서명의 강도는 원영상에 따라 달라지므로, 적합한 신호를 제안된 방법에 의해 산출 할 수가 있었다. 실험 결과, 제안된 방법이 주파수 영역에서 기존의 사설 방식에 비해 우수한 변조방지와 낮은 가시성을 보임을 나타내었다.

A wavelet-based image watermarking scheme is proposed, based on the insertion of pseudo-random codes in the frequency domain. The original image is required for the watermark detection. The 'strength' of the signature to be embedded depends on the image to be marked, thus fitting signal capacity. The experimental results prove that the method is more tamper resistant and less perceptible for any type of images than other well-known private methods in the frequency domains.
