Abstract
We propose a simple, efficient technique for continuously adapting tim e-frequency and time-scale representations over time. The procedure co mputes a short-time quality measure of the representation for a range of values of a free parameter and estimates the optimal parameter valu e maximizing the quality measure via interpolation.
