    Abstract: 近年來數位影像浮水印的藏匿技術廣受熱烈探討。儘管浮水印技術的發展至今已趨
    發點,並配合YUV 色彩系統,利用離散餘弦轉換將彩色影像由空間域轉換至頻率域,
    The hiding of digital watermarks has been an interesting problem for many researchers
    in recent years. Although many watermarking techniques were proposed successfully to
    deal with both bi-level and gray-level watermarks, it is necessary to develop a robust
    watermarking method for the color watermarks.
    The purpose of this proposal is to develop a frequency-domain-based watermarking
    method in which the color watermarks can be treated. In the proposed method, the YUV
    color system is first combined with the discrete cosine transformation, and then the color
    images in the time domain are transformed into the frequency domain. After the proper
    treatment, the frequency coefficients of the color watermarks are hidden into the
    middle-low- frequency coefficients of the color images. In the hiding process, the
    robustness of the middle-low- frequency is developed into a favorable property to resist the
    ravages of various image processing. Finally, a series of experiments will be conducted to
    verify the practical efficacy of our purpose.
