An example that illustrates the importance of shift-invariance is image denoising by thresholding where the lack of shift-invariance causes pseudo-Gibbs phenomena around singularities.In addition to shift-invariance, it has been recognized that an efficient image representation has to account for the geometrical structure pervasive in natural scenes. In this direction, several representation schemes have recently been proposed

说明：  Aitken迭代程序,类似于简单迭代法,但由于简单迭代法.(Aitken Iterative procedure, similar to the simple iterative method, but due to simple iterative method.)

小波时频画图工具包，能较好地画出小波变换地时频图。(wavelet time-frequency drawing tool kits can be used to paint wavelet transform to the time-frequency map.)

matlab中指数拟合的源程序 很好 很有用(the matlab in exponential fitting good source useful)
