Abstract :
ROI (region of interest) in an image or video signal contains important information and attracts more attention of an image viewer. It is desirable to insert robust watermark in ROI to give better protection of digital image. This paper describes a region specific spatial domain scheme where watermark information is embedded into the most valuable area of the cover image. The regions are selected by quad tree decomposition of host image. Simulation results validate watermark embedding in the most valuable areas of the image. Simulation results also show that the proposed scheme is robust against a wide range of attacks available in StirMark 4.0 package.
