Algorithm of steganography based on YCbCr model and traditional ARQP algorithm

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 algorithm, the improved algorithm has three advantages. They have low-time complexity, low influence on the quality of carrier pictures and high-attacking ability to resist raw-quick-pairs (RQP).
