Efficient color image watermarking using homomorphic based SVD in DWT domain

This paper proposes a robust image watermarking approach using homomorphic based SVD in the DWT domain. The DWT is utilized to divide the host image into non-overlapping bands. The reflectance component of sub-band LL is extracted using homomorphic transform for each color (red, green and blue). The embedding watermark is done by applying SVD on the reflectance component of the sub-band LL. The results of the proposed watermarking approach are...
