    Abstract :

    The main goal of image watermarking is to hide specific information into host image such that the presence of the watermark cannot be realized by human visual. The good watermarking algorithm design should meet three criteria, i.e. the rightful ownership protection, robustness against the image manipulations, and watermark imperceptibility. This paper outlines a brief survey over different image watermarking techniques. According to this paper, the basic image watermarking schemes are accomplished in spatial domain and transform domain. Further the transform domain also depends on the transform like DCT, DFT, DWT and SVD. The details of all types of approaches are focused in this paper and the pros and cons are also discussed more clearly.
