An Adaptive Visible Watermarking Algorithm for BTC Compressed Images

Nur Mohammad, Xingming Sun and Hengfu Yang    

Abstract: The development of modern communication technology, demand for digital image, audio, video and other digital contents transmission and storage are increasing rapidly. To protect digital product and ensure the secure transfer of the digital content become important issue in every fields. The researcher developed many visible watermarking algorithms; these are some specific fields. But can’t applicable of the digital image perfectly. In this research, An Adaptive Visible Watermarking Algorithm for BTC compressed images presented. BTC one of the effective and real time application for the image compression compare with transform domain and other data hiding techniques. Existing BTC-based visible data hiding algorithms do not fully exploit visual perception of the host images. That is why cannot obtain high hiding capacity and high visual quality of watermarked-images and visible watermark images. To obtain high visual quality of watermarked images and good perceptual visible watermark image, an adaptive scaling factor and embedding factor calculated by exploiting luminance and texture masking characteristics of digital images. This study is useful for modern communication technology. An Adaptive Visible Watermarking Algorithm for BTC compressed images is presented in the paper. For the more, the experimental results proved that the algorithm adaptive visible hiding information capacity is very high. So, the visual quality of watermarked-images and visible watermark image is very good.
