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