摘要
为了恢复在分形数据压缩过程中丢失的信息 ,从而获得分形数据压缩不变性 ,本文提出了一种基于小波变换技术估计和分析恢复数据参数的方法 .该方法有效地解决了应用传统故障诊断方法对恢复数据进行分析时存在误差的问题 。
In order to resume the “noise” information lost in the process of fractal data compression and obtain the invariance properties of fractal data compression, the paper provides a method to estimate and analyze parameters of the recovered data based on wavelet transform technique. The method resolves effectively the existing problem in analyzing the recovered data with conventional fault diagnostic methods, and enlarges the application fields of fractal data compression technique.
