Applying of the method of texture segmentation on the base laws’ energy maps for the digital watermarking
Nowadays protecting of copyright from illegal usage is highly required because of the growing popularity of the internet. One of the technologies that can protect multimedia message from being stolen is the digital watermarking (DWM). The main property of the method is transparency that means that a mark must not be seen by a naked eye. It is known that the most suitable place for DWM is an area with high textures because it makes a mark more inconspicuous for a human eye. Thus, for making a digital watermark more stable and invisible we can apply the container segmentation by texture features and use received data for spotting an appropriate place for a watermark. In the paper we made general analysis of the texture segmentation methods and classified them. The method of texture segmentation on the base of Laws` energy maps was described more carefully. We also made the description of the function of autocorrelation, which helps in spotting the areas with more grainy structure. The paper gives the results of tests of this function and has data about how accuracy rate may affect the time of segmentation process execution
