A Novel Steganography Algorithm Based on Motion Vector and Matrix Encoding
The modification of most traditional steganography algorithms based on motion vector is relatively high. After analyzing these steganography algorithms, we propose a novel steganography algorithm. The information is embedded into the optimal component (horizontal component or vertical component) of the motion vector with large amplitude. The main contributions of this scheme are as follows: First, our algorithm decreases the modification rate of motion vector by using the matrix encoding technique; second, the video quality is high, because we select the optimal component of the motion vector by using phase angle to embed information. The simulation results show that the proposed algorithm can not only decrease the modification rate of motion vector, but also achieve high video quality and embedding capacity.
