본 논문은 컬러 영상을 위한 윤곽선 기반 적응형 워터마킹(CAWCI)을 제안한다. RGB 공간이 있는 컬러 이미지는 먼저 해당 YCbCr 공간으로 변환됩니다. 휘도(Y) 이미지와 두 개의 색차(Cb 및 Cr) 이미지는 각각 윤곽선 도메인으로 변환됩니다. 워터마크는 마지막으로 세 이미지의 가장 큰 세부 하위 대역의 등고선 계수에 삽입됩니다. 한편, CAWCI에는 대비 감도 기능과 워터마크 시각적 마스크가 채택되어 있기 때문에 내장된 워터마크는 눈에 띄지 않습니다. 반면, 내장된 워터마크는 등고선 변환에서 라플라시안 피라미드(LP)의 확산 특수성으로 인해 매우 견고합니다. LP의 고유한 변환 구조를 활용하여 워터마크 유무를 판별하는 해당 워터마킹 검출 알고리즘을 제안한다. 실험 결과는 워터마킹 비가시성과 워터마킹 견고성 측면에서 CAWCI의 유효성을 보여줍니다.

Abstract: This paper proposes a contourlet based adaptive watermarking for color images (CAWCI). A color image with RGB space is firstly converted to its YCbCr space equivalent; a luminance (Y) image and two chrominance (Cb and Cr) images are subsequently transformed into contourlet domain respectively; the watermark is embedded into the contourlet coefficients of the largest detail subbands of three images lastly. On the one hand, the embedded watermark is imperceptible because contrast sensitivity function and watermark visual mask are adopted in our CAWCI. On the other hand, the embedded watermark is very robust due to the spread specialty of Laplacian pyramid (LP) in contourlet transform. The corresponding watermarking detection algorithm is proposed to decide whether the watermark is present or not by exploiting the unique transform structure of LP. Experimental results show the validity of CAWCI in terms of both watermarking invisibility and watermarking robustness.

AB - This paper proposes a contourlet based adaptive watermarking for color images (CAWCI). A color image with RGB space is firstly converted to its YCbCr space equivalent; a luminance (Y) image and two chrominance (Cb and Cr) images are subsequently transformed into contourlet domain respectively; the watermark is embedded into the contourlet coefficients of the largest detail subbands of three images lastly. On the one hand, the embedded watermark is imperceptible because contrast sensitivity function and watermark visual mask are adopted in our CAWCI. On the other hand, the embedded watermark is very robust due to the spread specialty of Laplacian pyramid (LP) in contourlet transform. The corresponding watermarking detection algorithm is proposed to decide whether the watermark is present or not by exploiting the unique transform structure of LP. Experimental results show the validity of CAWCI in terms of both watermarking invisibility and watermarking robustness.
