数字水印技术在古典家具数字博物馆版权保护中的研究

近年来,古典家具越来越受到人们的青睐。但是目前还未见有关针对古典文物家具数字博物馆的相关研究报道。本文首先介绍了数字博物馆的特点以及所构建的明清古典文物家具数字博物馆,然后运用基于混沌理论的Logistic映射置乱方法对水印图像进行加密,以及变换域算法中基于DCT域的数字水印方法对数字博物馆的数字图像进行了版权保护,并利用Matlab软件进行水印图像的嵌入、提取和检测实验,取得了较好的效果,说明数字水印技术在文物家具图像版权保护方面具有很好的作用。

Digital Watermarking Technique Research In The Construction of Ming And Qing Dynasties Classical Cultural Relics Furniture Digital Museum

In recent years,classical furniture more and more get the favour of people.But now there are not yet see any study of the classical cultural furniture digital museum of related report.This paper firstly introduces the characteristics of digital museum and the Ming and qing dynasties classical cultural relics furniture digital museum what we build,then use the method of Logistic mapping scrambling watermark image encryption based on chaos theory,and dct-based digital watermarking method to protect the copyrigth of our museum＇s digital image,we use of Matlab software embedded,extraction and picture test,and obtained good results.Digital watermarking in digital image copyright protection that has good function.
