Stability estimates for adaptive focused time-frequency transforms
Pierre Warion, Bruno Torrésani
This contribution is a follow-up of a recent paper by the authors on adaptive, non-linear time-frequency transforms, focusing on the STFT based transforms. The adaptivity is provid…

A class of non linear adaptive time-frequency transforms
Pierre Warion, Bruno Torrésani
This paper introduces a couple of new time-frequency transforms, designed to adapt their scale to specific features of the analyzed function. Such an adaptation is implemented via…
