La transformée en ondelette discrète (en anglais Discrete Wavelet Transform, ou DWT) est une technique utilisée dans la compression de données numériques avec ou sans perte (JPEG2000). La compression est réalisée par approximations successives de l information initiale du plus grossier au plus fin. On réduit alors la taille de l information en choisissant un niveau de détail.
