An Efficient Visible Watermarking for Copyright Protection Using Discrete Wavelet Transform

The objective of this project is to use a novel method for generic visible watermarking with a capability of lossless image recovery. This method is based on one-to-one compound mapping algorithm. The compound mappings are proved to be reversible, which allows for lossless recovery of original images from watermarked images. The mappings may be adjusted to yield pixel values close to those of desired visible watermarks. Different types of visible watermarks, including opaque monochrome and translucent full color ones, are embedded as applications of the proposed generic approach. To increase the visual perception Discrete Wavelet Transforms is used.Experimental results show that our method provides a higher embedding capacity compared to the other algorithms proposed in the literature.
