基于莫尔条纹隐藏图像动态显隐方法的研究
|
摘要
目前已有的信息隐藏防伪技术,存在着防伪技术复杂、防伪性能不佳及防伪系数较低等不足.为了提高防伪性能,并使显隐信息更加丰富,针对防伪图像的动态显示,提出了一种莫尔纹隐藏图像的动态显隐方法.基于莫尔纹机理,构建图像的插帧算法,利用该算法处理动态信息图,将隐藏信息嵌入到载体图像中,根据隐藏信息与显隐光栅之间的匹配原理,进行了动态显隐光栅片的制作,完成了隐藏图像的动态化显示.该动态显隐方法可以应用在防伪印刷工艺中,提升印刷品的高附加值.
At present,there exists so many technologies of information hiding and anti-counterfeiting,and there are deficiencies such as complex anti-counterfeiting technology,poor anti-counterfeiting performance,and low anti-counterfeiting coefficient.In order to improve anti-counterfeiting performance and hide the information more abundant,Combining with the dynamic display of anti-counterfeiting images,moire pattern hidden image dynamic explicit method is proposed.Based on moire mechanism,an image interpolation frame algorithm is constructed,this algorithm can be used to process dynamic information images,and the hidden information is embedded into the carrier image.According to the matching principle between the hidden information and the obscure grating,a dynamic visible and hidden grating is performed,the dynamic display of hidden images was completed finally.The anti-counterfeiting method is applied to the anti-counterfeit printing process,and the high added value of the printing product can be promoted.
