AB  - This paper presents a new approach to deal with the translation- and 
      scale-invariant problem of the discrete wavelet transform (DWT). Using a 
      signal-dependent filter, whose impulse response is calculated by the first two 
      moments of the original signal and a scale function of an orthonormal wavelet, we 
      adaptively renormalized a signal. The renormalized signal is then decomposed by 
      using the algorithm of the conventional DWT. The final wavelet transform 
      coefficients, called adaptive wavelet invariant moments (AWIM), are proved to be 
      both translation- and scale-invariant. Furthermore, as an application, we define 
      a new textural feature in the framework of our adaptive wavelet decomposition, 
      show its stability to shift and scaling, and demonstrate its efficiency for the 
      task of scale-invariant texture identification.
