摘要 通过对DWT的分析,引入静态小波变换,从对静态一维离散小波变换的分解、重构,到对静态二维离散小波变换的分解、重构,运用实例作比较,说明静态离散小波变换的优点,并提出需要改进的地方. The Maximal merit of stationary wavelet is invariance of translation, by the analysis to DWT, the research draws out the SWT. By decomposing and reconstructing for one-dimension of SWT and two-dimension of SWT, using example to demonstrate the virtue of SWT, some advice for the improvement are given.
