摘要：

提出一种对一类JPEG图像隐秘算法的多类分类方案。首先对多类分类的可能性做定量分析。简单介绍了几种压缩分类方法,其次进行了多类分类的算法设计,最后对实验结果进行了分析。该方案在重加密特征的基础上,利用Fridrich J等提出的压缩分类方法,实现了对该类隐秘图像的多类分类,准确性和运行效率高。

Abstract:

A multi-class classification program for the secret algorithm of the JPEG images is proposed.First,a quantitative analysis is made of the possibility of multi-class classification,then some compression classification methods are introduced,and a multi-class classification algorithm is designed,and finally experimental results are analyzed in detail.On the basis of re-encryption and by using the classification method of compression proposed by Fridrich J.this design realizes the multi-class classification of a hidden image with high accuracy and efficiency.
