Este artigo propõe uma marca d'água adaptativa baseada em contorno para imagens coloridas (CAWCI). Uma imagem colorida com espaço RGB é primeiro convertida em seu espaço equivalente YCbCr; uma imagem de luminância (Y) e duas imagens de crominância (Cb e Cr) são posteriormente transformadas em domínio de contorno, respectivamente; a marca d’água é incorporada nos coeficientes de contorno das subbandas de maiores detalhes de três imagens, por último. Por um lado, a marca d'água incorporada é imperceptível porque a função de sensibilidade ao contraste e a máscara visual da marca d'água são adotadas em nosso CAWCI. Por outro lado, a marca d’água incorporada é muito robusta devido à especialidade de propagação da pirâmide Laplaciana (LP) na transformada de contorno. O algoritmo de detecção de marca d'água correspondente é proposto para decidir se a marca d'água está presente ou não, explorando a estrutura de transformação única do LP. Os resultados experimentais mostram a validade do CAWCI em termos de invisibilidade e robustez da marca d'água.

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.
