摘要: 在分析经典Farid高阶统计量模型基础上,采用离散Haar小波对其线性预测模型相关性区域进行定位描述,并改进其偏向不一致缺陷,通过数学推导提出R-Farid线性预测模型;并提出了R-Farid高阶统计量模型。实验结果显示,其具有更好的隐写检测效果。Abstract: Through theoretical analyzing the classical Farid high order statistic linear prediction model based on discrete Haar wavelet,a R-Farid linear prediction model is proposed by revising its inconsistent relativity area,and then it is defined as Farid high order statistic model,a R-Farid high order statistic model is designed.Experimental results show that it really improves the steganalysis accuracy rate.
