  One of the effective methods for the preservation of copyright ownership of
digital media is watermarking. Different watermarking techniques try to set a
tradeoff between robustness and transparency of the process. In this research
work, we have used color space conversion and frequency transform to achieve
high robustness and transparency. Due to the distribution of image information
in the RGB domain, we use the YUV color space, which concentrates the visual
information in the Y channel. Embedding of the watermark is performed in the
DCT coefficients of the specific wavelet subbands. Experimental results show
high transparency and robustness of the proposed method.
