将均值偏移算法嵌入到粒子滤波的跟踪框架中.该算法克服了粒子滤波计算量较大的缺点,同时也克服了均值偏移算法容易陷入局部最大且无法恢复的缺点.实验表明该算法有很好的实时性和鲁棒性.

LSB（Least  Significant  Bit）算法是将秘密信息嵌入到载体图像像素值的最低有效位，也称最不显著位，改变这一位置对载体图像的品质影响最小。-LSB (further Significant Bit) algorithm is to embed the secret information carrier image pixel values of the Least Significant Bit, also known as the Least Signi
