| 摘 要： | 针对传统抗原始快速配对(ARQP)算法的不足,该文以YCbCr模型和传统的ARQP算法为基础,结合亮度Y和RGB三色分量的关系转换公式,给出了ARQP改进算法--AR.QP213.该算法利用HVS对于不同颜色敏感程度的差异,在保证图像质量的情况下尽可能地扩展ARQP密写的颜色空间.与原ARQP算法相比,改进算法具有时间复杂度低、对载体图像质量影响小、抵抗原始快速配对(RQP)攻击能力强等优点.

| Abstract: | In view of the shortcomings of the anti-raw-quick-pairs(ARQP) algorithm,based on YCbCr model and traditional ARQP algorithm,and combining the relations conversion formula between luminance Y and RGB three-color components,this paper provides ARQP's improved algorithm called ARQP213.The algorithm utilizes difference of the sensitive intensity of different colors of HVS to expand ARQP's color space as much as possible in the condition of guaranteeing the quality of pictures.Compared with the original ARQP alg... |
