We further propose a possible fast hybrid fractal encoding algorithm which combines existing fast search methods, statistical normalization and frequency domaincomparison.
The comparison among various methods of parameter estimation shows that the least-squares fitting method in the time domain is more accurate one.
各种参数估值方法的比较表明，时间域最小二乘拟合法较为精确。
