Watermarking

产生BCH码多项式，其中码字长度为N，消息长度为K(BCH code generated polynomial, which codeword length N, message length K)

matlab程序，对一个混沌系统进行仿真。 lyapunov.m是计算的主程序；qi_hyper.m是一个例子（qi系统），利用qi_hyper_lyap.m计算所有李氏指数，利用qi_hyper_lyapDim.m计算分形维数。其他系统稍作改正就可使用。经验证程序比其他计算李氏指数的更为有效精确。(matlab program for a simulation of chaotic systems. lyapunov.m are calculated in the main program qi_hyper.m are a case in point (qi system), the use of all qi_hyper_lyap.m calculated Lyapunov exponent, using qi_hyper_lyapDim.m calculated the fractal dimension. Other systems can be used to make some corrections. Experience in the certification process than any other computing Lyapunov exponent of the more effective precision.)
