Abstract:

Directly modifying the motion vector for information hiding easily leads to the accumulation effect of inter-frame distortion. The reference frame interval parameter K is introduced to change the reference structure of the P frame and an adaptive two-dimensional histogram modification (A2DHM) algorithm based on motion vector is proposed by analyzing the influence of K on the motion vector distribution of the P frame. The algorithm keeps its directionality immovable as much as possible while modifying the motion vector. A adaptive strategy proposed by this paper is used to select the optimal migration center point (OMCP) in the m-neighborhood of zero point for motion vector modification.

Key words: video steganography, reversible data hiding, motion vector, histogram modification
