Design and Realization of Digital Watermark Experimental System

This thesis discussed the design and realization of digital watermark experiment system,and mainly studied the watermark embedding,extraction and attack experiments which use all kinds of multimedia information as carrier.The thesis designed six experimental modules including carrier preprocess,watermark preprocess,watermark attack,image watermark,audio/video watermark and other watermark,and presented that the user interface of experimental system should display visually the executing process of algorithms step by step,and the experiment instructor and software document should be written in detail,so the system not only can be used for course demo and course experiment,but also can be used as software prototype for development.In experiment teaching,the system has achieved good results.
