Abstract :
We compute AM-FM representations for multicomponent,
nonstationary images using a statistical component model. Components
are isolated with a filterbank comprising frequency and orientation selective
channels. The modulating functions for each component are estimated
from the channel responses using localized nonlinear operators followed
by optimal MMSE estimators. We also demonstrate reconstruction from
the representation.
