密写编码技术以占用较多的载体数据为代价来减少对载体数据的修改量,从而降低信息隐藏引起的失真. 本文首先将密写编码方法的构造转化为一个数据的稀疏表示问题,然后提出出密写编码构造算法. 利用该构造算法可得到一系列密写编码方法,并进一步研究密写编码的组合形式,在不同占用率条件下获得了良好的编码性能,优于矩阵密写编码和游动密写编码.
-Steganography to occupy more vector data to reduce the cost of the modifications of the vector data, thereby reducing the information hiding distortion caused by coding techniques. Firstly, the structure of steganography encoding method into a data sparse problem, and then proposed steganography encoding construct the algorithm using the construction algorithm available steganography encoding method, and further study of the combination of steganography encoding in the occupancy rate under the conditions of a good coding performance is better than the encoding matrix steganography and swimming steganography encoding.
