A modified wavelet transform, the scale-adapted wavelet transform (SAWT), is proposed. The scale factor is adaptively changed according to the local structure of the input signal. The transformed image keeps the same dimensions as the input signal without losing the meaningful multiresolution representation. Some simple applications of the SAWT are discussed.
